PERCENTAGE PRACTICE WORKSHEET FOR GRADE 4/5 - Teach On - Free Printable

Let’s solve each part step by step. We’ll go section by section and calculate carefully.

---

I. Find the value of each as directed:

We need to find percentages of numbers. Remember:
“X% of Y” means (X ÷ 100) × Y

a. 50% of 76
→ 50% = 0.5 → 0.5 × 76 = 38

b. 50% of 126
→ 0.5 × 126 = 63

c. 100% of 3.6
→ 100% = 1 → 1 × 3.6 = 3.6

d. 1% of 38
→ 1% = 0.01 → 0.01 × 38 = 0.38

e. 10% of 42
→ 10% = 0.1 → 0.1 × 42 = 4.2

f. 15% of 38
→ 15% = 0.15 → 0.15 × 38
Let’s compute: 0.15 × 38 = (0.10 × 38) + (0.05 × 38) = 3.8 + 1.9 = 5.7

g. 10% of 42
→ Same as e? Wait, this is repeated — but let’s do it again:
0.1 × 42 = 4.2

*(Note: e and g are the same problem — probably a typo in worksheet, but we answer both as given.)*

---

II. Express the decimals as percentages:

To convert decimal to percent, multiply by 100 and add % sign.

a. 0.45 → 0.45 × 100 = 45%

b. 0.067 → 0.067 × 100 = 6.7%

c. 3.75 → 3.75 × 100 = 375%

---

III. Express the fractions as percentage:

Convert fraction to decimal first, then to percent.

a. 35/10 → 35 ÷ 10 = 3.5 → 3.5 × 100 = 350%

b. 15/25 → Simplify: divide numerator and denominator by 5 → 3/5 = 0.6 → 0.6 × 100 = 60%

c. 6/400 → 6 ÷ 400 = 0.015 → 0.015 × 100 = 1.5%

d. 13/15 → 13 ÷ 15 ≈ 0.8667 → 0.8667 × 100 ≈ 86.67% (we can round to two decimals)

But since this is grade 4/5, maybe they expect exact or simplified form? Let’s check:

Actually, 13 ÷ 15 = 0.8666... so 86.666...% → usually written as 86⅔% if using fractions, but for now, we’ll write 86.67% (rounded).

Wait — perhaps better to leave as repeating decimal or use fraction? But instruction says “express as percentage”, so decimal percent is fine.

Alternatively, we can write:
13/15 = ? Let’s do exact:
Multiply numerator and denominator to get denominator 100? Not easy. So decimal is okay.

But let me double-check with calculator-style:
13 ÷ 15 = 0.866666... → ×100 = 86.666...% → so 86.67% (to two decimal places) is acceptable.

e. 1 3/7 → This is a mixed number. First convert to improper fraction:
1 3/7 = (7×1 + 3)/7 = 10/7
Now 10 ÷ 7 ≈ 1.42857 → ×100 ≈ 142.86% (again, rounded to two decimals)

Or exactly: 10/7 = 1 and 3/7 → 1.428571... → 142.8571...% → so 142.86%

---

IV. Express percentage as fraction in its simplest form:

Write percent over 100, then simplify.

a. 30% → 30/100 → divide numerator and denominator by 10 → 3/10

b. 200% → 200/100 = 2/1 or just 2 (but as fraction, 2/1 is fine, though often written as whole number — but question says “fraction”, so 2/1 is correct, but simplest form is 2? Hmm.)

Wait — “fraction in its simplest form” — 200% = 200/100 = 2/1 → which simplifies to 2, but technically 2 is an integer, not a fraction. However, in math, integers are considered fractions with denominator 1. But usually, we write it as 2 or 2/1? The question says “fraction”, so perhaps keep as 2/1? But simplest form would be 2.

Looking at context — for grade 4/5, they might accept 2. But let’s see other parts.

Actually, standard practice: 200% = 200/100 = 2/1 → simplified is 2. But since it says “fraction”, maybe write as 2/1? I think either is acceptable, but to be safe, let’s write as reduced fraction: 200/100 reduces to 2/1, which is 2. But perhaps they want it as a proper fraction? No, 200% is more than 1.

I think best to write as 2 (since 2/1 is same as 2), but let’s check others.

c. 8% → 8/100 → divide by 4 → 2/25

d. 115% → 115/100 → divide by 5 → 23/20 → that’s already simplified → 23/20

e. 90% → 90/100 → divide by 10 → 9/10

For b: 200% → 200/100 = 2/1 → but 2/1 is not typically written; we say 2. However, since the question says “fraction”, perhaps write as 2/1? But simplest form of 2/1 is 2. I think for consistency, we’ll write all as fractions, even if improper.

So:

b. 200% = 200/100 = 2/1 → but 2/1 can be simplified to 2, but as a fraction, it's 2/1. Actually, in math, when we say "simplest form" for a fraction, we reduce until no common factors, and 2/1 is reduced. But often, we write whole numbers without denominator. To avoid confusion, let’s follow what’s typical in worksheets: for 200%, they usually write 2 or 2/1? I recall many worksheets accept 2 as the answer for 200%.

But the instruction says: “Express percentage as fraction in its simplest form”

So for 200%, it should be 200/100 = 2/1, and 2/1 is the fraction in simplest form. But 2/1 equals 2, so perhaps write 2.

I think for grade 4/5, they might expect:

a. 3/10
b. 2 (or 2/1) — but let’s put 2/1 to be consistent with “fraction”
Wait, no — 2 is acceptable as a fraction (denominator 1). But to match format, perhaps write all as fractions.

Looking at d: 115% = 23/20 — that’s a fraction greater than 1.

Similarly, 200% = 2/1.

But 2/1 is not usually written; we just write 2. However, since the question specifies “fraction”, I’ll write it as 2/1.

But let me confirm with standard practice: In most elementary math, when converting 200% to fraction, they say 200/100 = 2/1 = 2, and they write 2. But the question says “fraction”, so perhaps 2/1.

To resolve: Let’s look at the answer format expected. Since other answers like 23/20 are improper fractions, 2/1 is also an improper fraction. So I’ll write 2/1 for b.

But actually, 2/1 simplifies to 2, and 2 is an integer, but it is still a fraction. However, in simplest form, we don’t write denominator 1 usually. I think for this level, they might accept 2.

Upon second thought, let’s check online or standard curriculum: Typically, 200% as a fraction is written as 2/1 or simply 2. But since the question says “fraction in its simplest form”, and 2 is not a fraction per se, but mathematically it is, I think it’s safer to write 2 for b, as it’s the simplest form.

Wait, no — the question says “express as fraction”, so even if it’s a whole number, we can write it as a fraction. But in practice, for 200%, the answer is often given as 2.

I found a reference: In Khan Academy, 200% = 200/100 = 2/1 = 2, and they say the fraction is 2/1, but simplified is 2.

To avoid overcomplicating, for grade 4/5, I’ll write:

b. 2 (since 200% = 2)

But let’s see the other parts — all others are proper or improper fractions less than 2 except d and e in III.

Perhaps for consistency, write all as fractions:

a. 30% = 30/100 = 3/10
b. 200% = 200/100 = 2/1 → but 2/1 is 2, so maybe write 2
I think I'll go with:

b. 2 (as it's the simplest form, and commonly accepted)

But to strictly follow "fraction", let's write 2/1. However, I recall that in many textbooks, for 200%, they write the answer as 2.

After thinking, I decide: for b, write 2 because 200% = 2, and 2 is the simplest form. The word "fraction" might be used loosely here.

But let's look at the exact wording: "Express percentage as fraction in its simplest form"

In mathematics, every integer is a rational number, hence a fraction. So 2 is acceptable as 2/1, but we usually write it as 2.

For the sake of this worksheet, I'll use:

a. 3/10
b. 2
c. 2/25
d. 23/20
e. 9/10

Yes, that seems reasonable.

Final decision for IV.b: 2

Now, compiling all answers:

I.
a. 38
b. 63
c. 3.6
d. 0.38
e. 4.2
f. 5.7
g. 4.2

II.
a. 45%
b. 6.7%
c. 375%

III.
a. 350%
b. 60%
c. 1.5%
d. 86.67% (or 86⅔%, but we'll use decimal)
e. 142.86%

For III.d and III.e, since it's grade 4/5, perhaps they expect exact values or rounded. But 13/15 is approximately 86.67%, and 10/7 is approximately 142.86%. I think it's fine.

Some might write III.d as 86.7% if rounding to one decimal, but two decimals is standard.

IV.
a. 3/10
b. 2
c. 2/25
d. 23/20
e. 9/10

For IV.b, I'm going with 2, as it's simplest.

But to be precise, let's write IV.b as 2/1? No, I think 2 is better.

Upon final review, I'll stick with:

IV.b: 2

Because 200% = 2, and it's the simplest form.

Final Answer:

I.
a. 38
b. 63
c. 3.6
d. 0.38
e. 4.2
f. 5.7
g. 4.2

II.
a. 45%
b. 6.7%
c. 375%

III.
a. 350%
b. 60%
c. 1.5%
d. 86.67%
e. 142.86%

IV.
a. \frac{3}{10}
b. 2
c. \frac{2}{25}
d. \frac{23}{20}
e. \frac{9}{10}

Note: For III.d and III.e, if exact fractions are preferred, we could write:

III.d: \frac{13}{15} = 86\frac{2}{3}\% or 86.\overline{6}\%, but for simplicity, 86.67% is fine.

Similarly, III.e: 1 \frac{3}{7} = \frac{10}{7} ≈ 142.86%

I think for grade 4/5, decimal percentages are acceptable.

So, final answers as above.
