Question

Which equation represents this number sentence? three less than one-fifth of a number is 28.

Answer 1

see explanation

Explanation:

let the number be n , then 3 less than one- fifth of the number is

`(1)/(5)` n - 3 = 28 ← equation representing the sentence

to find the number

add 3 to both sides

`(1)/(5)` n = 31 ( multiply both sides by 5 to clear the fraction )

n = 5 × 31 = 155
