80 and 100
90.
97 is the largest prime number below 100.
When calculating with percentages, one method is to first convert them to decimals or fractions. Using the decimal method, 80%=0.8 and 100%=1. Therefore, the literal translation of you question would read "0.8 x 1 = 0.8". 0.8 is the decimal answer. If you wanted a percentage answer, you would convert this back to 80%. Kind of a nonsense question, though. You usually do not take percentages of percentages.
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
It is 5 : ) addy
Once with a remainder of twenty
What number goes into 49 and 100
100 multiplied by 80 is 8,000.
80 is equal to 80 because it is the same number....... :)ex. (79=79) (100=100)
The HCF of 27 and 80 is 1
Work out 1% of the number by dividing it by 100; then 2.25% of the number is 2.25 times this. eg 2.25% of 80 is: 1% of 80 = 80 ÷ 100 = 0.8 → 2.25% of 80 = 2.25 x (1% of 80) = 2.25 x 0.8 = 1.8 This is the same as considering: Percent means "out of 100" → 2.25 % = 2.25/100 (put the 2.25 over 100) → 2.25% of 80 = 2.25/100 x 80 = 1.8 (as before)
1
The number 80 means 100 percent 80/100 = 0.8 means 1 percent. 64/0.8 gives 80 percent, belonging to the number 64.
28% of 80 = 80*28/100 = 22.4
80 and 100
take the number and multiply it by .8 like .8x100 (80 percent of 100) = 80
