Since the denominators of the fractions are same, we just have to copy it, the denominator is 20. Then, we subtract the numerators, but, 16 - 18 is not right, thats why we take a 20 from the 8(whole number) and add it to the numerator of the first fraction, which is 20 + 16, equals to 36, Making the whole number of the first fraction 7 and the numerator 36, It is now 7 36/20 - 7 18/20, which is easy to answer, since we know that fractions with the same denominators, we just have to copy the denominator, so denominator is 20. then we subtract the whole number, since the whole number of the first fraction changed from 8 to 7, we subtract 7 and 7, which is 0, so there is no whole number left. Next, we subtract the numerators, at first it was 16 - 18, and we changed it to 36 - 18, which is 18. Making the answer, 18/20, last step is we reduce it to lowest term, which is 9/10.

8 16/20 - 7 18/20
7 36/20 - 7 18/20
36/20 - 18/20
18/20
9/10
