0.21 simplified as a fraction?
you move decimal point 2 places to the right21/100 this cannot be simplified further
that would be 21/100 but 21/100 cannot be simplified because they do not have a number in common. example:2/4 can be simplified because 2/4 divided by 2 would= 1/2 because 2 goes into 2, 1 time and 2 goes into 4, 2 times
