Answer:

Explanation:

To find the ratio of children to adults in the tour group, you can simply divide the number of children by the number of adults:

Ratio = Number of Children / Number of Adults

In this case, you have 9 children out of a total group size of 21. To find the number of adults, subtract the number of children from the total:

Number of Adults = Total - Number of Children

Number of Adults = 21 - 9

Number of Adults = 12

Now, you can calculate the ratio:

Ratio = 9 children / 12 adults

To simplify this ratio, you can divide both the numerator and denominator by their greatest common divisor, which is 3:

Ratio = (9 ÷ 3) children / (12 ÷ 3) adults

Ratio = 3 children / 4 adults

So, the ratio of children to adults in the tour group is 3:4.
