4/7 divide by 3/8 = 7/4 * 3/8 = 21/32
what did Alex do wrong? ASAP

Step-by-step explanation:

He should’ve flipped 3/8 to 8/3.

= 7/4 x 8/3 = 56/12

He should have done 4/7 * 8/3 = 32/21

Step-by-step explanation:

4/7 divide by 3/8 = 7/4 * 3/8 = 21/32

To divide 4/7 by 3/8, keep 4/7 and multiply by the reciprocal of 3/8, so do the multiplication below:

4/7 * 8/3

His mistake is using the reciprocal of the first fraction instead of the reciprocal of the second fraction.
