Question

0.75 is 1.5% of what number?

Answer 1

The answer is 50, and it can be solved using the percent proportion

Answer 2

The answer is:  " 50 " .
__________________________________________________

Note: 1.5% = (1.5)/100 = 1.5 ÷ 100 = 0.015 ; 

0.75 = (0.015)x ; solve for "x" ;

↔   (0.015)x = 0.75 ;

Multiply EACH SIDE of the equation by "1000" ; to simplify: 

         15x = 750 ; 

Divide each side of the equation by "15" ; to isolate "x" on one side of the equation; and to solve for "x" ; 

         15x / 15 = 750 / 15 ;

to get:     x = 50 ; which is our answer.
____________________________________
Let us check:  0.75 = (0.015)x ;  does this hold true when "x = 50" ?

→  0.75 = (0.015)x ;

↔ (0.015)x = 0.75 ;

    →  Plug in "50" for "x" to see if the equation holds true; 

    →  (0.015)*(50) = ? 0.75 ??

    →  Check using calculator ;

    →  (0.015)*(50) = 0.75 .  Yes!
