Part 1: Convert improper fractions to mixed numbers
To convert an improper fraction to a mixed number:
- Divide the numerator by the denominator.
- The quotient is the whole number part.
- The remainder becomes the new numerator over the original denominator.
Let’s go one by one:
① 11 ÷ 5 = 2 with remainder 1 →
2 1/5
② 25 ÷ 4 = 6 with remainder 1 →
6 1/4
③ 22 ÷ 6 = 3 with remainder 4 → but 4/6 can be simplified to 2/3 →
3 2/3
④ 37 ÷ 7 = 5 with remainder 2 →
5 2/7
⑤ 13 ÷ 4 = 3 with remainder 1 →
3 1/4
⑥ 29 ÷ 5 = 5 with remainder 4 →
5 4/5
⑦ 35 ÷ 8 = 4 with remainder 3 →
4 3/8
⑧ 58 ÷ 9 = 6 with remainder 4 →
6 4/9
⑨ 43 ÷ 7 = 6 with remainder 1 →
6 1/7
⑩ 27 ÷ 10 = 2 with remainder 7 →
2 7/10
⑪ 38 ÷ 12 = 3 with remainder 2 → 2/12 simplifies to 1/6 →
3 1/6
⑫ 19 ÷ 5 = 3 with remainder 4 →
3 4/5

Part 2: Complete the equivalent fractions
Equivalent fractions mean multiplying or dividing both numerator and denominator by the same number.
① 2/5 = 6/?
→ 2 × 3 = 6, so 5 × 3 = 15 →
15
② 4/9 = 16/?
→ 4 × 4 = 16, so 9 × 4 = 36 →
36
③ 5/11 = ?/88
→ 11 × 8 = 88, so 5 × 8 = 40 →
40
④ 3/5 = 12/?
→ 3 × 4 = 12, so 5 × 4 = 20 →
20
⑤ 2/5 = 4/?
→ 2 × 2 = 4, so 5 × 2 = 10 →
10
⑥ 6/18 = ?/3
→ Simplify 6/18 first: divide top and bottom by 6 → 1/3 → so ? =
1
⑦ 2/8 = 6/?
→ 2 × 3 = 6, so 8 × 3 = 24 →
24
⑧ ?/6 = 20/24
→ Simplify 20/24: divide by 4 → 5/6 → so ? =
5
⑨ 1/? = 6/30
→ Simplify 6/30: divide by 6 → 1/5 → so ? =
5
