Maths: Percentage :Expressing in Percentage

What I have learnt about Percentage. I'll take a question from my E-Learning Day Math Lesson.

Question

There are 27 girls and 23 boys in Person A's class.

a) Find the percentage of girls in Person A's class. 

b) Find the percentage of boys in Person B's class.

Solution(for A)

Find the total number of students.

27+23=50

Then, put the number of girls over the total number of pupils. It will create a fraction: 27/50

Multiply the fraction by 100%. 

27/50  x 100% = 54%

The percentage of girls in Person A's class is 54%

Solution(for B)

There are two methods.

Method 1

100%-54%=46%

Method 2

23/50 x 100% = 46%
