17 ½ % of 240
First option
Change the fraction ½
to a decimal. It would be 0.5 ( 1 divided by 2)
½=0.5
You will add the whole number 17 to the result.
17 + 05 = 17.5
Now you will divide by 100 (percent)
17.5 /100 To divide a
decimal by 100, move the decimal point two
places to the left.
17.5 /100 = 0.175 times 240
0.175 x 240 = 42
Second option
Change the percent to an improper fraction
17 ½= 35/2 (you have to multiply (2 x 17) plus 1 equals 35
over 2 ( keep the denominator). It will be 35/2. Put the other number (240) over 100 and
multiply.
35/2 x 240/100 = 42
