How do you increase 80 by 40 percent?

Answer 1

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

Answer 2

To increase 80 by 40%, you first convert 40% to a decimal by dividing it by 100, which gives you 0.40. Then, you multiply 80 by 0.40 to find the amount of the increase, which is 32. Finally, you add the increase to the original number: 80 + 32 = 112. So, increasing 80 by 40% results in a final value of 112.

Answer 3

80 x .40 = 32

Add 32 to 80
