These types of questions were always the most fun in early mathematics. Remember the clock? It's broken not only into hours but minutes as well.
Imagine that there are 60 seconds in one minute. So we know that an entire 60 seconds is 100% of a minute we can work back from there.
How many 20% would you need in order to make 100%? You would need 5 (5 x 20 = 100).
/ = per (60 seconds per 1 minute)
60 seconds/1 minute ÷ 5 periods/1 minute = 12 seconds/period
So 12 seconds would be exactly 20% of one minute.

There are 60 seconds in one minute. Therefore, 20 seconds is equal to 20/60 x 100 = 33.3 recurring (that is, 33.3333..) percent.
No. 1/20 is the same as 5%, not 20%. Percent means hundredths, so 20% is the same as 20/100, which simplifies to 1/5.
12 percent plus 20 percent equals 32 percent. To add one percentage to another simply add the numbers together and keep the percentage sign.
Expressed as a fraction, 20 percent is equal to 1/5 or one fifth.20% = 20/100 = 2/10 = 1/520/100 is 20 percent and that simplified is 1/520% = 20/100 which reduces to 1/5.
20 percent Solution Method: 1/5 * 100 = 100 / 5 = 20 % or 20 percent (both represent the same thing) Another Method: 1/5 = .20 .20 * 100 = 20 % or 20 percent (both represent the same thing)
