Question

A field is 60 m long and 40 m wide. What is the ratio between its length and perimeter. What is the value of the denominator - numerator in their lowest form.

Answer 1

Perimeter of the field = 2( length + breadth ) $=2(60+40)=200m$
Ratio of length and perimeter of the field $=60m:200m$

Simplifying it by dividing by $20$, we get the ratio $=3:10$

Thus , the value of denominator - numerator $=7$
