A juice vendor has a 5 l container of orange juice. Each glass has a capacity 250 ml. (a) How many full glasses can he serve before the container becomes empty?
(a) Given: Container capacity = 5 l = 5,000 ml Glass capacity = 250 ml
Formula: Number of glasses = Total capacity ÷ Glass capacity
Substitution: Number of glasses = 5,000 ml ÷ 250 ml
Calculation: Number of glasses = 20
Answer: The vendor can serve 20 full glasses before the container becomes empty.
Explanation
The chapter explains division of capacities. Container capacity = 5 l = 5,000 ml. Each glass capacity = 250 ml. Number of glasses = 5,000 ml ÷ 250 ml = 20 glasses.
Solution Steps
Step 1: Convert container capacity to ml: 5 l = 5,000 ml
Step 2: Each glass capacity = 250 ml
Step 3: Number of glasses = 5,000 ml ÷ 250 ml = 20 glasses
