Question

The ratio of number of girls to that boys in a school is 9:14. If the number of boys in a school is 1414, find.the number of girls in the school and the total number of students in the school​

Answer 1

Answer:

Number of girls = 909

Explanation:

Number of girls = x

Number of boys = 1414

Ratio = 9:14

Let's proportionate it,

therefore, 9:14::x:1414

$9 \times 1414 = 14 \times x \\ (9 \times 1414) \div 14 = x$

By cancelling values,

$(9 \times 101) \div 1 = x$

As anything divided by 1 is the same number itself,

$9 \times 101 = x \\ 909 = x \\ x = 909$

The number of the girls = 909
