Answer» Answer: Question given, $\frac{ - 100}{121} + \frac{ - 23}{99}$ As per the question we are given TWO fraction so we have to find the LCM of both the fraction by prime factorisation. Now, As we know the lcm of both the fraction is 1089 We have to bring the denominator same Like this, $\frac{ - 100}{121} \times 9 = \frac{ - 900}{1089}$ $\frac{ - 23}{99} \times 11 = \frac{ -253 }{1089}$ Now lets US add them!! $\frac{ - 900}{1089} + \frac{ - 253}{1089}$ $= \frac{ (- 900) + (- 253)}{1089}$ $= \frac { - 1153}{1089}$ $= 1 \frac{64}{1089}$ Hope it helps you mate!!
