Question

1/5 equals the quotient of a number and 15. Find the number.

Answer 1

Hi Abby,

Let's use the variable x to represent the unknown number.

The quotient of this number and 15 can be written as: x

15

Since we know this quotient is equal to 1 , we can write and solve the following to determine the unknown number: 5

1 = x

5 15

Multiply the numerator and denominator by 3 to find x:

1 • 3 = x

5 • 3 15

x = 3

The unknown number is 3.
