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:

`(3)/(4)-(1)/(8)`

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

`(3)/(4)-(1)/(8)=(6)/(8)-(1)/(8)`

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

`(6)/(8)-(1)/(8)=(6-1)/(8)=(5)/(8)`

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