Answer 2

To simplify the given fractions, we need to find the greatest common divisor (GCD) of the numerator and the denominator for each fraction and then divide both the numerator and denominator by the GCD. This will give us the simplified form of each fraction. Here are the simplified fractions:

1. 15/21: GCD(15, 21) = 3 Simplified: (15/3) / (21/3) = 5/7

2. 10/25: GCD(10, 25) = 5 Simplified: (10/5) / (25/5) = 2/5

3. 21/24: GCD(21, 24) = 3 Simplified: (21/3) / (24/3) = 7/8

4. 4/100: GCD(4, 100) = 4 Simplified: (4/4) / (100/4) = 1/25

5. 12/16: GCD(12, 16) = 4 Simplified: (12/4) / (16/4) = 3/4

6. 3/84: GCD(3, 84) = 3 Simplified: (3/3) / (84/3) = 1/28

7. 9/54: GCD(9, 54) = 9 Simplified: (9/9) / (54/9) = 1/6

So, the simplified fractions are: 5/7, 2/5, 7/8, 1/25, 3/4, 1/28, 1/6.
