Question

Answer 1

Hi Jennifer, first lets turn the 3/8 into a decimal.

 

 Divide 8 into 3.00 to get its decimal equivalent

 

When you divide your answer is 0.375

 

Now Multiply $728.00 By 0.375 and your answer is:$273.00

 

Now subtract the $273.00 from $728.00 and $455.00 is left over.

____________________________________________________

 

The second way is to subtract 3/8 from 8/8 (8/8 = 100%) so,

 

8/8-3/8= 5/8

 

Now here Divide the 8 into 5.00

 

Your answer will be 0.625

 

Now multiply the $728.00 by 0.625 the remaining that has to be kept and remainder paid

 

           $728.00

            x 0.625

          __________

        = $455.00

 

       so:

               $728.00

               - $455.00

              _________

            =$ 273.00   ->Must be paid
