# 13 in textbook

13.
Suzanne answered 1/10 + 3/10 this way:
1/10 + 3/10 = 4/20
a) Suzanne is wrong because it is not written like that.
b) The answer would be like this:
1/10+ 3/10 = 4/10 simplify it to: 4/10 = 2/5 4÷ 2 from 2/5, 10 ÷ 2 to the 5 .

    Good Job Explaining. But can you put it in picture to make it less confusing?
