Answer:
180 cm³
Step-by-step explanation:
A glass is 1/3 full. Then 75cm³ of orange juice is poured in. The glass is now 3/4 full. What is the total volume of the glass?
Let
x = total volume of the glass
1/3x + 75 = 3/4x
75 = 3/4x - 1/3x
75 = 9x-4x/12
75 = 5/12x
x = 75 ÷ 5/12
x = 75 × 12/5
= 900/5
= 180 cm³
x = 180 cm³
