Let's solve each problem step by step. The goal is to
convert mixed numbers to improper fractions.
🔷 How to Convert a Mixed Number to an Improper Fraction:
A mixed number has the form:
$$
a \frac{b}{c}
$$
where $a$ is the whole number, $b$ is the numerator, and $c$ is the denominator.
To convert it to an improper fraction:
1. Multiply the whole number ($a$) by the denominator ($c$).
2. Add the numerator ($b$) to that product.
3. Place the result over the original denominator ($c$).
So:
$$
a \frac{b}{c} = \frac{(a \times c) + b}{c}
$$

Now let’s solve each one:
---
1) $ 2 \frac{2}{3} $
- $ 2 \times 3 = 6 $
- $ 6 + 2 = 8 $
- So: $ \frac{8}{3} $
✔ Answer: $ \frac{8}{3} $
---
2) $ 3 \frac{1}{4} $
- $ 3 \times 4 = 12 $
- $ 12 + 1 = 13 $
- So: $ \frac{13}{4} $
✔ Answer: $ \frac{13}{4} $
---
3) $ 4 \frac{2}{5} $
- $ 4 \times 5 = 20 $
- $ 20 + 2 = 22 $
- So: $ \frac{22}{5} $
✔ Answer: $ \frac{22}{5} $
---
4) $ 2 \frac{3}{5} $
- $ 2 \times 5 = 10 $
- $ 10 + 3 = 13 $
- So: $ \frac{13}{5} $
✔ Answer: $ \frac{13}{5} $
---
5) $ 1 \frac{3}{2} $
- Note: This is an
improper fraction already in mixed form, but we'll follow the rule.
- $ 1 \times 2 = 2 $
- $ 2 + 3 = 5 $
- So: $ \frac{5}{2} $
✔ Answer: $ \frac{5}{2} $
*(Note: $1 \frac{3}{2}$ is equivalent to $2 \frac{1}{2}$, but since the question asks for conversion, we keep it as $ \frac{5}{2} $.)*
---
6) $ 3 \frac{3}{4} $
- $ 3 \times 4 = 12 $
- $ 12 + 3 = 15 $
- So: $ \frac{15}{4} $
✔ Answer: $ \frac{15}{4} $
---
7) $ 1 \frac{2}{4} $
- $ 1 \times 4 = 4 $
- $ 4 + 2 = 6 $
- So: $ \frac{6}{4} $
We can simplify this: $ \frac{6}{4} = \frac{3}{2} $, but unless asked to simplify, we can leave it as $ \frac{6}{4} $. However, usually we reduce.
But since the instruction is just to convert to improper fraction, either is acceptable. But standard is to reduce.
✔ Answer: $ \frac{3}{2} $ (simplified)
---
8) $ 3 \frac{4}{7} $
- $ 3 \times 7 = 21 $
- $ 21 + 4 = 25 $
- So: $ \frac{25}{7} $
✔ Answer: $ \frac{25}{7} $
---
9) $ 2 \frac{5}{7} $
- $ 2 \times 7 = 14 $
- $ 14 + 5 = 19 $
- So: $ \frac{19}{7} $
✔ Answer: $ \frac{19}{7} $
---
10) $ 1 \frac{3}{6} $
- $ 1 \times 6 = 6 $
- $ 6 + 3 = 9 $
- So: $ \frac{9}{6} $
Simplify: $ \frac{9}{6} = \frac{3}{2} $
✔ Answer: $ \frac{3}{2} $
---
✔ Final Answers:
| Problem | Answer |
|--------|--------|
| 1) $ 2 \frac{2}{3} $ | $ \frac{8}{3} $ |
| 2) $ 3 \frac{1}{4} $ | $ \frac{13}{4} $ |
| 3) $ 4 \frac{2}{5} $ | $ \frac{22}{5} $ |
| 4) $ 2 \frac{3}{5} $ | $ \frac{13}{5} $ |
| 5) $ 1 \frac{3}{2} $ | $ \frac{5}{2} $ |
| 6) $ 3 \frac{3}{4} $ | $ \frac{15}{4} $ |
| 7) $ 1 \frac{2}{4} $ | $ \frac{3}{2} $ |
| 8) $ 3 \frac{4}{7} $ | $ \frac{25}{7} $ |
| 9) $ 2 \frac{5}{7} $ | $ \frac{19}{7} $ |
| 10) $ 1 \frac{3}{6} $ | $ \frac{3}{2} $ |
> 💡 Tip: Always check if the improper fraction can be simplified. For example, $ \frac{6}{4} $ and $ \frac{9}{6} $ both reduce to $ \frac{3}{2} $.
