Oh, dude, 19 divided by 6 is like 3.16666666667. But, like, who really needs all those decimal places anyway? It's not like we're splitting a pizza here. Just round it to 3.17 and call it a day.

19 / 20 (19 divided by 20) = 0.95Now convert the decimal to a percentage by multiplying it by 100: 0.95 * 100 = 95%

Numbers become a repeating decimal when dividing by ANY whole number, except when (if the division, expressed as a fraction, is in simplest terms) the denominator has no prime factors other than 2 and 5.The reason for this is related to the fact that our decimal system is base 10, and 10 is made up of the factors 2 and 5. Any denominator with other factors cannot be exactly expressed as a terminating decimal. That includes denominators 3, 6, 7, 9, 11, 12, 13, 14, 15, 17, 18, 19, 21, etc.
