Why? Because that's what "complement" means. For example, if 60% of a certain population are adults, the remainder - 40% - are not adults. That's the complement. The "100%" refers to the total population in this case.
The complement of 10 percent is 90 percent. In probability and percentage terms, the complement refers to what remains when a certain percentage is subtracted from 100 percent. Therefore, 100 percent minus 10 percent equals 90 percent.

To subtract 80 percent from a number, first calculate 80 percent of that number by multiplying it by 0.80. Then, subtract the result from the original number. For example, if the number is 100, you would calculate 80 percent as 100 × 0.80 = 80, and then subtract: 100 - 80 = 20. The final result is the number after subtracting 80 percent.
to find percent deviation you divide the average deviation into the mean then multiply by 100% . to get the average deviation you must subtract the mean from a measured value.
firstly, find 15 per cent of 450, by dividing 450 by 100 and then multiplying it by 15. After you've found this, subtract this from 450. :)

65% (35+65 = 100%)
Whether the change is an increase or decrease . . . -- Divide the new number by the original number. -- Multiply the result by 100. -- Subtract 100. -- Now you have the percent of change.

Multiply it by (100 percent minus 9 percent). (100 - 9) percent = 91% = 91/100 = 0.91 45,000 x 0.91 = 40,950
Take the old value and subtract from the new value, then divide by the old value. Multiply by 100. That number representsthe percent change.
To decrease a number by 25 percent, first, calculate 25 percent of that number by multiplying it by 0.25. Then, subtract the result from the original number. For example, if the original number is 100, 25 percent of 100 is 25, so you would subtract 25 from 100, resulting in 75.
If you take 208.56 and divide it by 100 you can find 1%, which is 2.0856 if you now multiply it by 15 you can find 15%, which is 31.284. Now all you need to do is subtract 31.284 (15%) from 208.56, which gives you 177.276
First you subtract the new number from the original number then divide it by the original number and multiply that by 100 original-new __________*100 original
