Answer:
6
Step-by-step explanation:
When dividing fractions, you want to multiply the reciprocal of the fraction (flip the fraction so the numerator is the denominator and the denominator is the numerator).

If you don't know how to multiply fractions as well, I will show you now.
Since 4 is just 4/1, I will convert just so you can visually see how I multiply.

When multiplying fractions, you multiply the numerators and the denominators.
So it would be 4 * 12 & 1 * 8

Your fraction is 48/8. But it can be simplified, let's divide 48/8. That equals 6!
