Answer 2

To subtract fractions, you need to have a common denominator. Let's go through each subtraction problem:

1. 3/10 - 2/25: To find a common denominator, we can multiply the denominators: 10 * 25 = 250. Now, we need to adjust the numerators accordingly: (3/10) * (25/25) - (2/25) * (10/10) = 75/250 - 20/250 = (75 - 20)/250 = 55/250. The result is 55/250, which can be simplified further.

2. 2/9 - 2/15: The common denominator here is 9 * 15 = 135. Adjusting the fractions: (2/9) * (15/15) - (2/15) * (9/9) = 30/135 - 18/135 = (30 - 18)/135 = 12/135. The result is 12/135, which can also be simplified.

3. 7/20 - 7/30: The common denominator for this problem is 20 * 30 = 600. Adjusting the fractions: (7/20) * (30/30) - (7/30) * (20/20) = 210/600 - 140/600 = (210 - 140)/600 = 70/600. The result is 70/600, which can be simplified as well.

Please note that the simplified fractions are provided for each problem, but you can further simplify them if necessary.
