Percentage, Base, Rate worksheet - Free Printable

Let's solve each of these percentage problems using the easy percentage method, which involves breaking down percentages into simpler parts (like 10%, 5%, 1%, 25%, etc.) and using mental math.

---

🔹 Remember:

- 10% = divide by 10
- 1% = divide by 100
- 50% = divide by 2
- 25% = divide by 4 (or half of 50%)
- 5% = half of 10%
- 100% = the whole number

---

Now let’s solve each one step by step:

---

#### 1. 10% of 145
→ Divide 145 by 10
= 14.5

---

#### 2. 1% of 116
→ Divide 116 by 100
= 1.16

---

#### 3. 50% of 108
→ Half of 108
= 54

---

#### 4. 100% of 104
→ The whole number
= 104

---

#### 5. 5% of 120
→ First find 10% of 120 = 12
Then half of that = 6
So, 5% = 6

---

#### 6. 10% of 5
→ Divide 5 by 10
= 0.5

---

#### 7. 25% of 28
→ 25% is a quarter → divide by 4
28 ÷ 4 = 7

---

#### 8. 50% of 64
→ Half of 64
= 32

---

#### 9. 5% of 84
→ 10% of 84 = 8.4
Half of that = 4.2
So, 5% = 4.2

---

#### 10. 25% of 8
→ Divide 8 by 4
= 2

---

#### 11. 1% of 67
→ Divide 67 by 100
= 0.67

---

#### 12. 5% of 12
→ 10% of 12 = 1.2
Half of that = 0.6
So, 5% = 0.6

---
