Question

andre says that 5 3/4 + 2 1/4 = 7 1/2 because 7 4/8 = 7 1/2 identiy his mistake draw a picture to prove that he is wrong

Answer 1

The mistake he makes is by saying 3/4 + 1/4 = 4/8

The denominators stay the same when adding fractions, and the denominators must be the same value.

So instead, he should have 3/4 + 1/4 = 4/4 = 1

Overall, 5 3/4 + 2 1/4 = 5+2+1 = 8
