Answer:
4 1/4
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.
