$\sf \implies Perecentage \: ( \% ) = \dfrac{Number \: Given}{Total \: Number} \: \times 100$

Substitute the values,

$\sf \implies Perecentage \: ( \% ) \: of \: boys= \dfrac{16}{25} \times 100$

Answer 2

Given :

• Total Number of Students in the class = 25 students
• Numbers of boys in the class = 16 boys

To Find :

• Percentage of Boys in the Class.

Solution :

✰ As we know that, Percentage is given by Number Given/Total Number × 100 . Now in this question, Number of boys is 16 and Total Number of Students are 25 . So we will substitute the given values in the formula to find the percentage of boys.

⠀⠀⠀

⟼ Boys% = Total Boys/Total Number × 100

⟼ Boys% = 16/25 × 100

⟼ Boys% = 16 × 4

⟼ Boys% = 64%

⠀⠀⠀

So, Percentage of boys in the Class is 64%
