If 75% of a number is 255 and 20% of the same number is 68, find 95% of that<br> number.
Tanzania [10]

Answer:

75% may also be expressed as 75/100=3/4 or as 0.75 as needed.

 

Let x = the number

 

Translate:

 "if 75% of a number is 60"       means

     (75/100)  *  x      =  60            [the word "of" usually means multiply]

     (3/4) x = 60                           [reduce or just write it this way]

        x  = 60(4/3)                       [multiply both sides by  4/3]

        x = 80
