Question

A photo frame is 60 cm wide and 1.8 m long. The ratio of its width to its perimeter in lowest form is

• A. 1 : 2
• B. 1 : 3
• C. 1 : 4
• D. 1 : 8

Answer 1

The correct option is D 1 : 8

The photo frame is in a rectangular shape.
Hence, its perimeter = 2(L+B)
Given, L = 1.8 m
B = 60 cm = 0.6 m
Therefore, perimeter = 2(1.8 + 0.6)m
= 2(2.4)m
= 4.8 m
Ratio of width to perimeter = $\frac{0.6}{4.8}$
= $\frac{1}{8}$
