Question

A drink bottle is 3/8 full. It contains 240 millilitres of water. How much water does the bottle contain when it is half-full?​

Answer 1

Answer: 320 mL

Step-by-step explanation:

Given information

The bottle is currently 3/8 full

Current Volume = 240 mL

Concept:

Imagine the water in the bottle being separated into 8 parts

Currently, 3 parts are being occupied

Determine the volume for 1 part

3 parts = 240 mL

1 part = 240 / 3 = 80 mL

Determine the volume for half-full (4 parts)

1 part = 80 mL

4 parts = 80 × 4 = $\Large\boxed{320~mL}$

Hope this helps!! :)
