Answer 4

The correct answer is 7/10.

Answer 5

To find the percent of zebras at the zoo, you can use the formula:

(percent of zebras) = (number of zebras) / (total number of animals) * 100

In this case, the number of zebras is 4 and the total number of animals is 80. Substituting these values into the formula, we get:

(percent of zebras) = (4 / 80) * 100

Simplifying the fraction, we get:

(percent of zebras) = 0.05 * 100 = 5

Therefore, the percent of animals at the zoo that are zebras is 5%.

Answer 6

To find the decimal that represents the number of grapes that are green, divide the number of green grapes by the total number of grapes.

Number of green grapes = 50
Total number of grapes = 250

Divide 50 by 250:
50 / 250 = 0.2

Therefore, the decimal that represents the number of grapes that are green is 0.2.

Answer 7

To find the fraction of the population that are children, we need to convert the percentage to a fraction.

The given percentage is 22%. To convert it to a fraction, we need to divide 22 by 100.

22 ÷ 100 = 11/50

Therefore, the fraction that represents the proportion of the population that are children is 11/50.
