For every 4 adults at the beach one afternoon, there were

3 children. How many children were at the beach if there

were 8, 12, 16, or 20 adults at the beach?

16

1.20

Number of Adults

4

Number of Children

There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.

Step-by-step explanation:

After reviewing the information given for solving the question, we notice that the ratio of adults in relation with the number of children at the beach is 4:3. In that case, for finding the number of children for every specific number of adults, we do the following calculations:

1. For 8 adults: 8/4 = 2 and using the ratio 4:3, we multiply by 2 and we get that the number of children is 6.

2. For 12 adults: 12/4 = 3 and using the ratio 4:3, we multiply by 3 and we get that the number of children is 9.

3. For 16 adults: 16/4 = 4 and using the ratio 4:3, we multiply by 4 and we get that the number of children is 12.

4. For 20 adults: 20/4 = 5 and using the ratio 4:3, we multiply by 5 and we get that the number of children is 15.

There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.
