Show how Carly can work out 171/2% of 240 in her head
KATRIN_1 [288]

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

There is another way . You can simplify

Cancel all the zeros that you have and start to reduce.

            6

7       12

35 x 24<span> 0   </span> =  42

2       10 0

 1          5

           1

17 ½ % of 240  =  42
