Question

Sari had 3/4 of a bag of pretzels. Her younger brother ate some, leaving her with 1/8 of a bag. What fraction of the bag did Sari brought eat?[M] 4/12[P] 2/4[R] 5/8[S] 7/8

Answer 1

In order to find the remaining amount in the bag, we need to subtract 1/8 from the fraction 3/4:

$\frac{3}{4}-\frac{1}{8}$

To do so, first let's put both fractions in the same denominator:

$\frac{3}{4}-\frac{1}{8}=\frac{6}{8}-\frac{1}{8}$

Now, let's subtract the numerators and find the result:

$\frac{6}{8}-\frac{1}{8}=\frac{6-1}{8}=\frac{5}{8}$

Therefore the correct option is the third one (R).
