Think of it in terms of $1.00. 1% of a dollar is one cent (.01) because there are 100 pennies in a dollar, 10% of a dollar is ten cents (.10)...think about it.

"bypass multiply" from the backside diagonally up as instruct below (each and all of the dots ··· are there simply by fact Yahoo removes greater areas.) one hundred············ninety 9 ···············/ ·······5·····9 ·······--- x --- ·······11··20 Multiply 20 circumstances 5. positioned one hundred above and to the left of 5 Multiply 11 circumstances 9. positioned ninety 9 above and to the marvelous of 9. one hundred > ninety 9. for this reason 5/11 > 9/20 Why does this artwork? to evaluate 5/11 and 9/20, you need to transform them to a uncomplicated denominator. the least complicated uncomplicated denominator is 11*20.: 5·····5····20····one hundred --- = --- * ---- = ----- 11···11 ··20····220 9·····9····11····ninety 9 --- = --- * ---- = ----- 20···20 ··11····220 Now which you have a uncomplicated denominator of 220, you may evaluate the two fractions by comparing the numerators, one hundred and ninety 9. observe which you do no longer in all possibility want to understand that the uncomplicated denominator is 220. you basically ought to understand that it exists. All you particularly care approximately is comparing 5*20 = one hundred and 9*11 = ninety 9. for this reason "bypass multiplying" became invented.

Percentage means "per 100", so 50% means 50 per 100,
or simply 50/100.
To change a percentage to a decimal you divide the percent by 100. (and remove the "%" sign).
If you divide 50 by 100 you get 0.5 (a decimal number).
The easiest way to divide by 100 is to move the decimal point 2 places to the left.
So:
From Percent To Decimal
move the decimal point 2 places to the left, and remove the "%" sign.
Example: Convert 8.5% to decimal
Move the decimal point two places: 8.5 -> 0.85 -> 0.085
Answer 8.5% = 0.085
SO: 20%= 20/100
=0.20 or 0.2

wow are you seriously asking a question like that ( seems like a waste of 5 points )
However, .2 is the decimal because you are comparing it to a 100 percent so you move the decimal place 2 places back.

Yep. Those answers are correct depending on how many digits you need. Both .2 and .20 are the same and are right so take your pick.
