I'm having problem understanding 2 2/7-1 1/3= can somebody help me with this question.

Answer 1

The first thing we do is change the fractions to equivalent fractions with the same denominator.

2 2/7 = 2 6/21
1 1/3 = 1 7/21

For this problem, we change 2 6/21 to 1 27/21

Now subtract the whole numbers and the numerators.

1 27/21 - 1 7/21 = 20/21

Answer 2

I'm not understanding 3/8 divide by 1/2, can somebody help me with this also. I just don't know what to do.

Answer 3

To divide fractions, we need to use the reciprocal of the divisor and multiply the numerators and the denominators.

(3/8) / (1/2)
(3/8) * (2/1) = 6/8 = 3/4
