Question

Ya yeet answer dis plzz

Answer 1

First, realize that you are doing $\frac{1}{2}$ divided by 4, which is the same thing as $\frac{1}{2} * \frac{1}{4}$. Multiplying the numerator and denominator across, you get $\frac{1}{8}$. There are four bags, each with this amount. But remember, Luke is keeping three of these bags, so the fraction of the original amount is 

$\frac{1}{8} * 3 = \dfrac{3}{8}$.

Alternatively, you can skip a step if you realize Luke is keeping $\frac{3}{4}$ of $\frac{1}{2}$.

Answer 2

He would keep 3/8 for himself. Hope it helps! :)
