please help me ​

Answer 1

Answer:

there are 150 children

Step-by-step explanation:

"there are  9 infants and 12 toddlers"

The number of children in the infant and toddler classes combined is 9 + 12 = 21.

21 children represent 14% of the total number of children in the day care program.

You are looking for the total number of children. The total number of children is 100% of the children.

Proportion:

Let x be the total number of children in the day care program.

21 children is to 14% as x children is to 100%

21/14 = x/100

Reduce the fraction on the left side.

3/2 = x/100

Cross multiply:

2x = 3 * 100

2x = 300

x = 150

Answer: there are 150 children

Answer 2

Answer:

150 children

Step-by-step explanation:

9 infants plus 12 toddlers= 21

Now put it into a percent proportion:

Percent proportion: Is/of=%/100 or a/w=p/100

21/14=x/100

now cross multiply:

Anser should be 150 children
