Mashutka [201]

Answer:

3/8 of the box

Step-by-step explanation:

On Friday Merinda uses 1/4 of the box of pancake mix to make pancakes.

On Saturday she uses 1 1/2 times as much pancake mix as Friday.

On Friday = 1/4 of the box

On Saturday = 1 1/2 × pancake mix as Friday

$\dfrac{3}{2}\times \dfrac{1}{4}\\\\=\dfrac{3}{8}$

Hence, 3/8 of the box of pancake mix does Merinda use on Saturday.
