The ratio of boys to girls in a group is 3 to 1 is there are 28 more boys then girls workout how many people their are it total
worty [1.4K]

Answer:

56 total

Step-by-step explanation:

Let the number of girls = x

Let the number of boys = 3x

x                      1

===       =    ==========

x + 28              3

Cross multiply

3x = x + 28                  Subtract x from both sides

3x - x = 28                   Combine

2x = 28                        Divide by 2

x = 28/2

x = 14

Girls = 14

Boys = 14 + 28 = 42

Is the ratio 3 to 1?

42/14 =  3/1 Yes it does

Total number

14 + 42 = 56
