Need solving 3 4/5 divided by ? = 2 5/7

You need to find the question mark.  Let's call this question mark, x.

3  4/5 ÷ x = 2  5/7

To get x, you need to multiply 2  5/7 and 3  4/5.

Then, make them into improper fractions.

(7 × 5) + 2 = 37/7    (It stays over 7)

(5 × 3) + 4 = 19/4    (It stays over 4)

37  ×  19                (Just multiply across)
 7       4

703
 28

Then, make this into a mixed number.

703 ÷ 28 = 25.1    or    25  1/10

Bc equals mb that should be your answer
