Question

In a school 3/8 of a students are boys. If there are 2400 students, Find the no. of girls in a school​

Answer 1

Answer:

check below

Step-by-step explanation:

So the initial number is 2,400.

The girls make up 45%.

If we convert the percentage to a decimal number between 0 and 1 then we can get the number of girls.

The number is 0.45 as you just need to a 0 before the number to turn it into a decimal.

If we use the decimal then we can times the initial number by it to find out what 45% of that number is.

After doing that we will have the answer which is 1,080.

Now we can find out how many boys there are.

The boys will be what is left of the population.

If we remove the girls from the initial number then we have our answer.

Which is 1,320.

Just the equations.

2,400 x 0.45

=1,0802.

2. 2,400 - 1080

=1,380

Answer 2

number of boys = 3/8 x 2400 = 900 boys

number of girls = 2400 - 900 = 1500 girls
