Question

This list shows the weight of three vegetables Mustapha bought to make stew.
• The potatoes weighed 2 7/8 pounds.
• The green beans weighed 1 1/8 pounds.
• The peppers weighed 2 1/2 pounds.
How many more pounds of vegetables would he need to have exactly ten pounds of
vegetables for his stew?​

Answer 1

Given:-

Weight of potatoes=$2\frac{7}{8}\text{pounds}=\frac{23}{8}\text{pounds}$

Weight of green beans=$1\frac{1}{8}\text{pounds}=\frac{9}{8}\text{pounds}$

Weight of peppers=$2\frac{1}{2}\text{pounds}=\frac{5}{2}\text{pounds}$

To Find:-

Weight of vegetables to have exactly 10 pounds

Steps:-

Let weight of vegetables be x kg. So,

$\frac{23}{8}+\frac{9}{8}+\frac{5}{2}+x=10\\\\\frac{23+9+20}{8}+x=10\\\\\frac{52}{8}+x=10\\\\x=10-\frac{52}{8}=\frac{80-52}{8}=\frac{28}{8}=3.5\text{pounds}$
