40% is 0.40
To take 40% of something, you multiply the something by 0.40
So the first question requires multiplying 200 X 0.40
The rest work the same way.

Wanna know a trick? Percent means the # out of a hundred, it's like a fraction. 85% is 85 over 100. 57% is 57 over 100. If you wanna calculate a percent # then divide that # by 100. Which means move the decimal 2 the left for 2 places. EZ
