Question

There are 8 girls for every 7 boys on a field trip.if there 56 girls on the trip how many students are on the trip

Answer 1

Well the first thing you need to do is set up a proportion.

8 girls 56 girls

-------- = -----------

7 boys x

Now what we have to do is find out what we multiplied by 8 to get 56.

Simply divide.

56 ÷ 8 = 7

So, we figured out that the magic number is 7!

So we multiply the boy number by 7

7 x 7 = 49

So this means that there are 49 boys on the field trip.
