Simplifying Fractions

To simplify the given fractions, we can find the greatest common divisor (GCD) of the numerator and denominator for each fraction and then divide both the numerator and denominator by the GCD.

1. 11/22: - The GCD of 11 and 22 is 11. - Simplified fraction: 11/22 ÷ 11/11 = 1/2

2. 10/25: - The GCD of 10 and 25 is 5. - Simplified fraction: 10/25 ÷ 5/5 = 2/5

3. 27/45: - The GCD of 27 and 45 is 9. - Simplified fraction: 27/45 ÷ 9/9 = 3/5

4. 9/12: - The GCD of 9 and 12 is 3. - Simplified fraction: 9/12 ÷ 3/3 = 3/4

5. 15/18: - The GCD of 15 and 18 is 3. - Simplified fraction: 15/18 ÷ 3/3 = 5/6

6. 24/30: - The GCD of 24 and 30 is 6. - Simplified fraction: 24/30 ÷ 6/6 = 4/5

7. 28/32: - The GCD of 28 and 32 is 4. - Simplified fraction: 28/32 ÷ 4/4 = 7/8

8. 21/15: - The GCD of 21 and 15 is 3. - Simplified fraction: 21/15 ÷ 3/3 = 7/5

Therefore, the simplified fractions are: 1/2, 2/5, 3/5, 3/4, 5/6, 4/5, 7/8, 7/5
