Question

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive? ​

Answer 1

There are 8 and 12 balloons for groups A and B, respectively.

Explanation:

The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:

Group A

`n_(A) = (2)/(2+3)\cdot (20)`

`n_(A) = 8`

Group B

`n_(B) = (3)/(2+3)\cdot (20)`

`n_(B) = 12`

There are 8 and 12 balloons for groups A and B, respectively.
