Well, isn't that a happy little question! To find out what percentage 40 is of 80, we simply divide 40 by 80 and then multiply by 100. So, 40 divided by 80 is 0.5, and when you multiply that by 100, you get 50%. That's a lovely half right there!
It is: 40/50 times 100/1 = 80%
Expressed as a percentage, 32/80 x 100 = 40 percent.
50% of 80= 50% * 80= 0.5 * 80= 4050percent of 80 is equal to 40
80% 40% 20% 10% %5
Method 1: 80 * .4 + 80 = 32 + 80 = 112 Method 2: 1. Add 100% to 40% = 140% 2. Convert 140% to decimal form: 140%/100 = 1.4 3. Multiple 1.4 * 80 = 112 <--- this is your answer. Note: The reason you add 100% to the 40% is because the phrase "increase 80" means you have to add 100% of 80 (which is 80 * (100%/100) = 80 * 1 = 80) to the increasing percentage (80 * 40% = 80 * (40%/100) = 80 * .4 = 32) to get your final answer (80 + 32 = 112). It looks like this in summary form: 80 * 100% = 80 * (100%/100) = 80 * 1 = 80 80 * 40% = 80 * ( 40%/100) = 80 * .4 = 32 80 + 32 = 112 You should be able to easily see that you can add 100% + 40% to get 140%, which converts to the decimal number 1.4 1.4 * 80 = your answer (i.e. 112). ============== Previous explanation: Right so you take 80, divide it by 10 (100 if you wanna stay with the full shabang) then multiply it by 4 (40 if you have already divided by 100) and the answer will be 32. add this number to 80. The answer is 112
