please help me im temporally brain dead or at least feel brain dead and i am having trouble understanding this

you should know: in all means in total, so simply you add everything up.

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

-- let me know if you have any questions regarding this.
