Question

A glass is 2/3 full. Then 40cm3 of orange juice is poured in. The glass is now 4/5 full. What is the total volume of the glass?

Answer 1

300 cm³

Explanation:

Volume of the glass filled with orange juice:

4/5-2/3= 12/15-10/15= 2/15

2/15 of glass = 40 cm³

Total volume of the glass:

40 cm³ ÷ 2/15= 40 cm³ × 15/2= 300 cm³
