1/10+1/5+5/9

First you must find the GCF (greatest common factor). In this case it is 90. This becomes your new denominator for all three fractions. You multiply each numerator by the number of times that the denominator divides into 90 ( 90 divided by 10 = 9...9 x
1 = 9...new fraction is 9/90) Follow this formula with each of the three fractions and then add numerators. The new fractions become : 9/90 + 18/90 +50/90 = 77/90. This is already reduced so this is your final answer
