Question

There are 14 girls in Sam's class of 25 students. He finds that the number of girls is of the total number of students of the class.

• A. $0.56$
• B. $0.28$
• C. $0.96$

Answer 1

The correct option is A $0.56$

Ratio of number of girls to total number of students of the class $=\frac{14}{25}$

On multiplying 4 in numerator and denominator of fraction, we get
$\frac{14}{25}=\frac{14\times 4}{25\times 4}=\frac{56}{100}$

There are two zeroes in denominator of the fraction $\frac{56}{100}$ so, we move decimal point to the left by two units.
$\frac{56}{100}=0.56$

$\therefore$ , Number of girls is 0.56 of the total number of students of the class.
