What you do is add up the coins in two piles 1. all the coins added up 2.coins that are more than 10 cents (or equal) take number 2 and put that in the numerator (top spot on a fraction) and take number 1 and put it on the denominator (bottom spot on a fraction) then simplify it if needed. 50/224 is the raw data simplify it for the real answer 25/112 is the simplest you can do so there's your answer. hope this helped :)
