The Waves swim team has a ratio of 14 boy: 12 girls. If there are 39 athletes, How many girls are there?

If 7 more boys join the Waves team, how many girls should be added to the team to maintain the same ratio of boys and girls.

1. 18 girls

2. 5 girls will be added to maintain the same ratio of boys and girls

Step-by-step explanation:

1. Boys : Girls = 14 : 12

14 + 12 = 26, 39/26 = 1.5

Boys: 14 x 1.5 = 21

Girls: 12 x 1.5 = 18

21 + 18 = 39 athletes, there are 18 girls on the 39 athletes.

2. Boys : Girls = 14 : 12

14 : 12

7   : ?

14 - 7 = 12 - ?

7 = 12 - ?

12 - 7

= 5
