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.

Even though we don't know the number yet, we need to give it some kind of label
so that we can work with it. We can call it anything. I'd like to call it ' G '.
The number we're looking for is ' G '.
Half of it is 1/2 G
The sum of that and 6 is 1/2 G + 6
Ten times that is 10 (1/2 G + 6)
The question says that's 8.
So 10 (1/2 G + 6) = 8
Divide each side by 10 : 1/2 G + 6 = 0.8
Subtract 6 from each side: 1/2 G = - 5.2
Multiply each side by 2 : G = - 10.4
That seems like a weird answer. We should check it.
The number: -10.4
Half the number: - 5.2
The sum of half the number and 6: -5.2 + 6 = +0.8
Ten times that sum: 8
Yep ! By golly, sho nuff, dV-dT and E to the X !
Everything checks out, and the mystery number is - 10.4
