Question

Hayley goes to school with a liter bottle of water she drink 1/4 of the bottle before school starts and 2/3 before the R Us for lunch but what fraction of the bottle does Halle drink after school starts but before lunch

Answer 1

We have:

- After she drinks 1/4 L and

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

so, she has 3/4 L remaining.

- If she then drinks 2/3 of this, will remain in the bottle:

$\frac{2}{3}\times\frac{3}{4}=\frac{6}{12}=\frac{1}{2}$

Answer: 1/2 of the bottle
