How do you increase 80 by 40 percent?

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
