Please help me on this math problem

-21/8 or  -2 5/8

Step-by-step explanation:

When dividing fractions by other fractions you use keep change flip, you keep the first fraction, change the division into multiplication and you flip the second fraction. We do this because we don't have to convert the fractions into decimals this was and its easier with fractions.

The problem changes to

3/8 times -7/1

Now we multiple the numerators together and the denominators together and then put it back into a fraction

3 * -7 = -21

8 * 1 = 8

-21/8

If you need it as a mixed number it is

-2  5/8

21/58.
