Yasmin purchased 6 heads of cabbage that each weighed 2 3/8 pounds. How much did the cabbage weigh all together?

nika2105 [10]

Answer:

14 $\frac{1}{4}$ pounds

Step-by-step explanation:

Here we have to use multiplication.

Yamin purchased 6 heads of cabbage.

The weight of each cabbage = 2 $\frac{3}{8}$

First let's convert the mixed fraction 2 $\frac{3}{8}$ to improper fraction

2 $\frac{3}{8}$ = $\frac{19}{8}$

The weight of 6 heads of cabbage = 6 x $\frac{19}{8}$

= 114/8

= 14 $\frac{2}{8}$

We can reduce 2/8 = 1/4

= 14 $\frac{1}{4}$

Thank you.
