Answer 1

Greetings!

Answer:

There are 840 boys who take part in sport activities.

Explanation:

First you can find the total amount of girls and boys in the school by simply dividing the total amount by 5, and multiplying the amount by 2 and 3 :

1800 ÷ 5 = 360

360 x 2 = 720 girls

3600 x 3 = 1080 boys

Firstly, you need to find the amount of girls in the 540 set. To do this you need to do the following equation:

Amount x fraction

So,

540 x
`(5)/(9)` = 300

So there are 300 girls in the 540 set.

To find the amount of boys in that you can simply subtract the amount of girls from 540:

540 - 300 = 240 boys who dont do sport.

Now you have the total amount of boys and the amount of boys that don't do sport, so now you can simply subtract the two from each other:

1080 - 240 = 840

So there are 840 boys who take part in sport activities!

Hope this helps!
