Question

In a class of 20 boys and 28 girls what percent
of the class are girls?​

Answer 1

Step-by-step explanation:

• Add the numbers together (e.g. 20+28=48 )

Divide the number you want as a percentage by the total. In this case, the number of girls: 28/48=0.583(3sf)

• Multiply by 100 to get a percentage. (e.g. 0.583∗100=58.3 )

Thus your answer is 58.3% of the class is female, rounded down to 58% if your teacher wants an exact integer.

Now, apply those same steps to any other number you need to find as a percentage. I'll give you another one just below, this time calculating the number of boys:

20+28=48

20/48=0.417(3sf)

0.417∗100=41.7

Thus 41.7% of the class is male.

As a final check, you can check to see that 41.7+58.3=100 . Seeing as that statement is true, you've carried out the percentage calculations correctly.
