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 = [tex]\Large\boxed{320~mL}[/tex]
