Answer:

[tex]2[/tex]

4th Answer is Correct

Step-by-step explanation:

[tex] - \frac{3}{4} + 2 \frac{3}{4} \\ \frac{ - 3}{4} + \frac{11}{4} \\ \frac{ - 3 + 11}{4} \\ = \frac{8}{4} \\ = 2[/tex]
4th answer is correct

Fraction -3/4 can be written as - 3/4 by extracting the negative sign.

Multiply 2 and 4 to get 8

add 8 and 3 to get 11

Since -\frac{3}{4} and \frac{11}{4} have the same denominator, add them by adding their numerators.

Add -3 and 11 to get 8

Divide 8 by 4 to get 2

so answer is 2
