First take out the 2 zero's. then you have 8x5. Multiply then add the 2 zero's. now you have 8500 which is the answer.

You could break down the corresponding elements. So you could add the 600 and the 200 giving 800. You could then add the 90 and the 2, giving 92. Then add the 800 and the 92, giving 892.
yes you can just multiply the 8 and the 5 then add all the zeros you have in the 800 to your answer. EX. 8x5=45 <-- your answer then add the 2 zeros your final answer is 4500

800 times 2 is exactly the same as 2 times 800+ 800+ 800--------=1600

It goes in 800 times.
Two hundredths [2/100] is the same as 2 in every hundred [or 2%]. 800 is the same as 8 x 100; or 8 hundreds. So "2/100 of 800" is 2 in every one of those 8 hundreds; or 2 x 8 = 16. To work this out divide 800 by 100 then multiply by 2. The answer is 16. Alternatively if it is a mental arithmetic question take off the 2 zeros and multiply by 2. 8 X 2 = 16
There are a few ways you can find what 800 increased by 30 percent is. 1) You can find 30% of 800 by multiplying 800 with 0.3 and then adding the two together. 2) you can just multiply 800 by 1.3 and directly get the answer. With these two, you should know that to convert a percentage into a decimal, you move the decimal point two spots over (123.4% = 1.234) 3) If you don't have a calculator, you can find an easy percentage and multiply it so you get 30% (for example: 10% of 800 = 80. 10% times 3 = 30% so 80 times 3 = 240. Therefore, 30% of 800 is 240.) In any case, the answer would be 1040.
If your 800 equals 100%, you simply multiply it by 14.52 800 x 14.52 = 11616
800 from my math class i know i am learning powers of ten
