The percentage of boys students

CONCEPT TO BE IMPLEMENTED

Percentage

In study mathematics the term percentage is used. It is denoted by the symbol %

The percentage is a number or ratio which is expressed as a fraction of 100.

PROCESS

In order to calculate percentage we divide the number by whole and multiply by 100

EVALUATION

Here it is given that in a school there are 70 boys and 280 girls

So total number of students

= 280 + 70

= 350

Hence the required percentage of boy students

$\displaystyle \sf{ = \frac{70}{350} \times 100 \: \% }$

$\displaystyle \sf{ = \frac{1}{5} \times 100 \: \% }$

$\displaystyle \sf{ = 20 \: \% }$
