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
