Answer 3

Sure, I can help you with that!

To subtract fractions, you need to have a common denominator. In this case, the common denominator is 20:

7/20 - 2/15

To convert 2/15 into an equivalent fraction with a denominator of 20, you can multiply the numerator and denominator by 4:

7/20 - (2/15 x 4/4) 7/20 - 8/60

Now that both fractions have a common denominator of 60, you can subtract the numerators:

7/20 - 8/60 = (21/60) - (8/60) = 13/60

Therefore, 7/20 - 2/15 = 13/60.
