Answer:​

Answer 1

(a) 15/3 = 100/x

(b) There are 20 toddlers in the class.

Explanation:

(a)

The total number of students is 100% of the students.

Let the total number of students be x.

15% of students is to 3 as 100% of students is to x.

15/3 = 100/x

(b)

15/3 = 100/x

Cross multiply the equation.

15x = 3 * 100

15x = 300

Divide both sides by 15.

x = 20

Answer: There are 20 toddlers in the class.
