Question

Sean what’s the ratio of boys to girls at his party to be 4 to 3. How many girls will have to come to the party if there will be 16 boys?

Answer 1

Answer: 12 girls


Step-by-step explanation:

4:3 is 4 boys per 3 girls.

16:x is 16 boys per x girls.

So, you divide 16 by 4, taking the 4 from the ratio (4:3) and you get 4.

( 16/4 = 4).

Then you take 4 and multiply by 3, taking the 3 from the ratio (4:3) and you get 12.

( 4 x 3 = 12 ).

So, 12 girls will have to come to the party. Hope this helps.
