Answer: 26/100 OR 0.26 (I would put the answer as a fraction)
Explanation:
We need both fractions to have the same denominator before we add them. The denominator of 6/100 is 100. The denominator of 2/10 is 10. We need to turn 10 into 100. To do that, we can do 10*10. This gives us 100. However what we do to the bottom must be done to the top therefore we have 20/100 + 6/100
Now the two fractions can be added together. 20/100 + 6/100 = 26/100.
Normally we would simplify this down to 13/50 but if you want it unsimplified 26/100 would be your answer.
