Examples of Unitary Method Questions
Practicing examples is the best way to understand the unitary method. Below are some simple questions commonly given in Class 7.
Example 1
If 6 notebooks cost $18, what is the cost of 1 notebook?
Solution
Cost of 1 notebook = 18 ÷ 6 = $3
Example 2
If 1 kg of sugar costs $4, what is the cost of 5 kg?
Solution
Cost of 5 kg = 4 Ã 5 = $20
Example 3
A car travels 60 km in 1 hour. How far will it travel in 3 hours?
Solution
Distance in 3 hours = 60 Ã 3 = 180 km
