Answer:

D.
1(7)/(8)

Explanation:

Okay when dividing fractions remember to use the KCF rule


(3)/(4) ÷
(2)/(5)

KEEP CHANGE FLIP


(3)/(4) x
(5)/(2)

So now me multiply the numerators and the denominators

3 x 5 = 15

4 x 2 = 8

So
(15)/(8) But that's not an answer choice so we convert the improper fraction into a mixed fraction

So, when divide 15 by 8 to get 1.875

Now we use the quotient/answer which is 1 as the whole number

The remainder will the numerator which is 7

And the denominator is always the denominator of the improper fraction itself which is 8

So we write the Improper fraction as is
1(7)/(8)

We can check our answer by converting the mixed fraction that we wrote back into its improper form


1(7)/(8)
((1x8+7))/(8) =
(15)/(8)
