you should know: in all means in total, so simply you add everything up.
answer:
1 + 2/4 + 3/4
- convert 1 to a fraction so its easier to add.
1 = 4/4 (must have the same denominator to add)
4/4 + 2/4 + 3/4
- add the numerators (top), NOT the denominators (bottom)
you get: 9/4 (this is an improper fraction, so you convert this into a mixed number)
9/4 = 2 1/4
FINAL ANSWER: (its a mixed number)
2 1/4
