Answers
Given data:
- The pieces of cloth are of 72 cm and 90 cm wide.
- Priyanka wants to cut both pieces into strips of equal width that are as wide as possible.
To find:
How wide should she cut the strips?
Step-by-step explanation:
In order to find the required width, we have to find the hcf (highest common factor) of 72 and 90.
Here 72 = 2 × 2 × 2 × 3 × 3
and 90 = 2 × 3 × 3 × 5
Thus hcf (72, 90) = 2 × 3 × 3 = 18
Answer:
Therefore she should cut the strips 18 cm wide.
