Answer:
The answer to your question is 24 cm³
Step-by-step explanation:
Data
Initial volume = 2/5
Additional volume = 42 cm³
Final volume = 4/7
the total volume of the glass = ?
Process
1.- Write a proportion to help you solve the problem
42 cm³ -------------------- 4/7 of the total
x ------------------- 7/7
2.- Solve the proportion
x = (7/7 x 42) / 4/7
3.- Simplification
x = 42 / 4/7
x = 168/7
x = 24 cm³
