2 / 10 = 20 / 100.

So 2 /10 + 2 / 10 = 4 / 10.

Simplify that to 2 / 5.

the awnser to your question would be 40/100 because sense you have to find the least common denominator (LCM) all you have to do is do 10*10 and 2*10 which equals 20/100 and THEN out do 20/100 plus 20/100 which equals 40/100.
