Question

Consider two strings AB and CD of lengths 5 cm and 20 cm respectively. Find $\frac{1}{4}$ of CD and hence find the ratio of one-fourth of CD to AB

• A. $\frac{1}{2}$
• B. $\frac{1}{3}$
• C. $\frac{1}{5}$
• D. $1$

Answer 1

The correct option is D

$1$

$\frac{1}{4}$ of CD = $\frac{1}{4}$ of 20 = 5

Ratio of one-fourth of CD to that of AB = $\frac{\frac{1}{4}CD}{AB}$

= $\frac{5}{5}$

= $1$
