Question

A picture frame is 80cm wide and 2.4m long. What is the ratio of its length to breadth?

• A. 3:1
• B. 1:3
• C. 24:80
• D. 80: 24

Answer 1

The correct option is A 3:1

Width of the picture frame = 80 cm
Length of the frame = 2.4 m
= $2.4\times 100$ = 240 cm
When finding the ratio of two quantities of the same kind, their units must be in the same units.
$\therefore$ Ratio of length to breadth = 240 : 80 = $\frac{240}{80}=\frac{80\times 3}{80\times 1}=\frac{3}{1}=3:1$
