Answer:
Fourth Option
Step-by-step explanation:
In order to find the answer to this question you need to change the mixed number into a improper fraction and then add by finding the least common denominator (LCD).
[tex]-\frac{3}{4} +2\frac{3}{4}[/tex]
Convert into improper fraction:
[tex]2\frac{3}{4} =4\times2=8+3=11[/tex]
[tex]-\frac{3}{4} +\frac{11}{4}[/tex]
Since how the denominators are the same you can just add numerators:
[tex]-3+11=8[/tex]
[tex]=\frac{8}{4}[/tex]
Reduce:
[tex]8\div4=2[/tex]
[tex]4\div4=1[/tex]
[tex]=\frac{2}{1}[/tex]
[tex]\frac{2}{1} =2[/tex]
Hope this helps.
