What is 2 1/2 + 1 3/4

17/4 or 4.25 or 4 1/4

4 1/4

Step-by-step explanation:

To do this problem, add the whole numbers together (2 + 1), and add the fractions together (1/2 + 3/4).

2 + 1 = 3

To add the fractions, you need to have common denominators. 1/2 = 2/4, so instead of writing 1/2 + 3/4, you now have 2/4 + 3/4.

Add the numerators together and put the same denominator.

So, 2/4 + 3/4 = 5/4.

This is an improper fraction, so to turn it into a mixed number, you put that 4 can go into 5 one time so the whole number is 1. Then there is one forth left. The one whole needs to be added to the original 3 we added together, so it's 4 and 1/4.
