Answer 2

90

Explanation:

let the number to be found be x then

23
`(1)/(3)` % of x = 21 ( change mixed number to improper fraction )

`((70)/(3) )/(100)` x = 21

`(70)/(300)` x = 21 ( multiply both sides by 300 to clear the fraction )

70x = 6300 ( divide both sides by 70 )

x = 90

Then 23
`(1)/(3)` % 0f 90 = 21
