The sum of one fifth of a number and 12 is 30. What a number

1 answer

Let's call the number "x".

The equation to represent the given information is:
1/5 * x + 12 = 30

To solve for x, we can first subtract 12 from both sides of the equation:
1/5 * x = 30 - 12
1/5 * x = 18

Next, we need to multiply both sides by 5 to isolate x:
5 * 1/5 * x = 5 * 18
x = 90

Therefore, the number is 90.
