How do you find 20% of something

Report as

20% is 1 fifth of something so an easy way to find 20% is to divide by 5.

E.g. 250/5=50, so 50 is 20% of 250.

Or you can divide by 10 and than multiply by two.

To find 20% of something, just take 20 and divide it by 100 and then multiply the answer with that "something.' For instance, lets say the "something" is 30 and you want 20% of it, just take 20/100 x 30, which would give you 6.

Multiply by .2 . In word problems, the word, "of" usually means to multiply by whatever is on the other side of the word, "of." Here, 20% OF 100 would yield an answer if you multiplied by the 20%. How do we turn a percentage (that 20 %) into a decimal so we can multiply it? Look closely at that percent sign. Imagine the spot where the slash hits the ground is a little foot that is going to kick the decimal point to the left from its present position when you remove the percentage sign. How far does the decimal point get kicked? Well, you kick it two places to the left, as represented by the two "0's" in the percentage sign. Thus, 20. becomes .20 because the dot got kicked two places to the left as the percentage sign was removed. Make sense? This is a backup way to remember it if you ever get confused.
