answer the following questions.
(a) 39 is 75% of what number?
(b) 27 is what percent of 60?

a) the number is 52

b)27 is  45 percent of 60

Step-by-step explanation:

(a) 39 = 75%  of x

    75/100 * x = 39

                  x = 39 * 100 /75

                     = 39 * 4/3 = 13 *4

                    = 52

b) 27 = x% of 60

   27 = (x/100) * 60

  x * 60 / 100 = 27

                  x = 27 * 100 / 60  

                      = 27 * 5/3 = 9 * 5

                      = 45

is there any photos or whatever?

so, converting firstly the mixed fractions to improper fractions and then "adding".
