What is 1 and 1/4 + 1 and 1/2

Firlakuza [10]

1 1/4 + 1 1/2

First change the mixed fractions into improper fractions.
Do this by multiplying the denominator by the whole number, then adding that to the numerator, leaving the denominator the same.

5/4 + 3/2

Now change the fractions so that they have a common denominator.
Here, you can use 4 as the CD, so leave the first fraction alone and just change 3/2.
3/2 = 6/4

5/4 + 6/4 = 11/4

11/4 can be changed into 2 3/4.

So the answer is 2 3/4 or 2.75.
