Detailed Solution

We have to add,
-1139+526+2
First, we will make the denominators of both the fractions same by multiplying denominator and numerator by 2, 3 and 78 respectively.
= −11×2 39×2 + 5×3 26×3 + 2×78 1×78 =− 22 78 + 15 78 + 156 78
Now, adding the numerators;
=− 22 78 + 15 78 + 156 78 = −22+15+156 78 = −22+171 78 = 149 78
Thus, the given statement is true.
Hence, option 1 is correct.
