1. 4/20
20 ÷ 5 = 4. Multiply top and bottom by 4: 1×4 / 5×4. = 4/20
2. 4/8
8 ÷ 2 = 4. Multiply top and bottom by 4: 1×4 / 2×4. = 4/8
3. 12/24
24 ÷ 6 = 4. Multiply top and bottom by 4: 3×4 / 6×4. = 12/24
4. 8/20
20 ÷ 5 = 4. Multiply top and bottom by 4: 2×4 / 5×4. = 8/20
5. 18/20
20 ÷ 10 = 2. Multiply top and bottom by 2: 9×2 / 10×2. = 18/20
6. 3/15
15 ÷ 5 = 3. Multiply top and bottom by 3: 1×3 / 5×3. = 3/15
7. 18/42
42 ÷ 7 = 6. Multiply top and bottom by 6: 3×6 / 7×6. = 18/42
8. 28/36
36 ÷ 9 = 4. Multiply top and bottom by 4: 7×4 / 9×4. = 28/36
9. 8
12 × 4 = 48, so the denominator was multiplied by 4. Do the same to the numerator: 2 × 4 = 8.
10. 21
11 × 3 = 33, so the denominator was multiplied by 3. Do the same to the numerator: 7 × 3 = 21.

Correction: Only multiplying or dividing keeps the fraction the same size.
Changes only the denominator.
Correction: Whatever you do to the bottom, do to the top.
