Word problems on division

Example 1

On average, 400 schools use a total of 12 666 800 litres of clean water per month. What is the average number of litres of clean water does each school use every month?

Solution

Total number of litres of water = 12 666 800 litres

Number of schools = 400

Divide the total number of litres of water by the number of schools as follows:

31667

400⟌ 12666800

‒1200

666

‒ 400

2668

‒ 2400

2680

‒ 2400

2800

‒ 2800

Therefore, each school uses an average of 31 667 litres of clean water every month.

Example 2

During the construction of a community market, a contractor set aside 110 253 350 shillings for paying 152 day workers equally. How much money did each day worker get and how much balance did the contractor remain with?

Solution

Total amount of money = 110 253 350 shillings

Number of day workers = 152

Divide using long division method as follows:

725350

152⟌ 110253350

Therefore, each day worker got 725 350 shillings and the contractor remained with 150 shillings.
