Question

How do I calculate what percent 7 is of 57?

Answer 1

 Percentage is simply a ratio, a fraction whose denominator is 100. It is an standard ratio

 

  So

      Just write the fraction 7/ 57 , now to get percentage value we have to multiply both numerator and denominator by some number that make denominator equal 100.

 

     57 is not divisible by 100.

 

      so simply carry the division of 7/57= 0.123, rounding off to thousandth. 

 

        7/57 = 0.123 = 12.3 %

          In last step, I multiplied 0.123 by 100, and divide by 100 for division by 100 , 1/100= 0.01= %

 

          % is equal to C, cent.

 

           

             So percentage is same as conversion of dollar to cents, and vice versa.

 

               % = c = 1/100 = 0.01

  

                 So convert any number to percentage value, we simply multiply by 100, and divide by 100

  

               then , replace the 1/100 by %

 

               n = n*100* 1/100= 100n%

 

                 like 1/4 * 100 * 1/100= 100/4 % = 25%

 

                     $ 1/4 = 25c ( quarter).

Answer 2

In order to calculate percentage, you have to think of parts to the whole. The whole is 57 and the parts would be 7 of those. The easiest way would be to divide 7/57. Which equals .122807 so move the decimal over to the right two places to get 12.28%.

Good hearing from you, Julie!

 

10% is 5.7 and 1% is 0.57 ... "stair-step" by subtracting 0.6 and adding 0.03: 5.7, 5.13, 4.56, 3.99 Answer ... Best wishes, ma'am :)
