Question

a box contains 1 3/4 pounds of pancake mix. Jada used 7/8 pound for a recipe. What fraction of the pancake mix in the box did she use?

Answer 1

Answer:

Jada used 1/2 of the pancake mix in the box

Step-by-step explanation:

we know that

$1\frac{3}{4}\ pounds$ -----> represent the 100% of the box

so

by proportion

Find what fraction represent $\frac{7}{8}\ pounds$

First convert mixed number to an improper fraction

$1\frac{3}{4}\ pounds=\frac{1*3+4}{4}=\frac{7}{4}\ pounds$

$\frac{100}{(7/4)}=\frac{x}{(7/8)}\\ \\x= 100*(7/8)/(7/4)\\ \\x=50\%$

Convert the percentage into fraction

$50\%=50/100=1/2$
