Forty-five children attend a preschool. The number of two-year-olds is one-half the number of three-year-olds. The number of four-year-olds is the same as the number of three-year-olds.

a. How many two-year-olds attend the preschool?
b. How many three-year-olds attend the preschool?
c. How many four-year-olds attend the preschool?

**9 students **are two-year-old, **18 **students are three-year-old and **18 **students are four-year-old.
What is equation?

**Equation **is defined as a **mathematical statement **that joins two expressions of equal value with the symbol "equal to." A formula would be 3x - 5 = 16, for instance . After solving this equation, we learn that the value of the variable x is 7.
Let number of 3 year old kid is x, number of 2 year old is x/2 and 4 year old is x.
The equation is
x + x + x/2 = 45
2x + 2x+ x /2 = 45
5x = 45 x 2
x = 90 / 5
x = 18
The two-year-old attend the preschool = 18 / 2 = 9
The three-year-old attend the preschool = 18
The four-year-old attend the preschool = 18
Thus, **9 students **are two-year-old, **18 **students are three-year-old and **18 **students are four-year-old.

There are 9 two-year-olds, 18 three-year-olds, and 18 four-year-olds attending the preschool. The calculations were based on defining the relationships between the age groups in an equation. By solving for the total, we found the quantities for each age group.
