When there is only one number repeating, put it over 9
0.8 repeating is 8/9
if there was 2 numbers repeating (.232323), u would put it over 99....23/99
if there was 3 numbers repeating (.234234234), u would put it over 999...234/999
The answer should be a repeating decimal. This is because any number you multiply by a repeating decimal automatically results in another repeating decimal.
