3 2/5 + 9 1/10= Simplest form
Talja [164]

Change each mixed fraction to improper

3 2/5 = 15/5 + 2/5 = 17/5

9 1/10 = 90/10 + 1/10 = 91/10

Find a common denominator. Multiply 2 to both numerator and denominator of 17/5

17/5(2/2) = 34/10

34/10 + 91/10 = 125/10

125/10

Simplify. Divide

125/10 = 12.5

12.5 is your answer

hope this helps
