Answer 1

12

Step-by-step explanation:

If you add the ratio you will get 8 and 1 in the ratio number represents

6 people so 5-3=2

Therefore, the no. of girls minus boys= 6×2=12

so you need 12 more boys to make it to be a ratio of 1:1

Answer 2

Answer: 12

Step-by-step explanation:

Find the girls:

48 x 5/8 = 30 girls

Find the boys:

48 x 3/8 = 18

In order for ratio to be 1:1 the amount of boys need to be equal to the girls:

18 + x = 30
x = 12

x = the amount of boys need to join to make the ratio 1:1
