Question

simplify: -16/9 + -5/12 + 7/18​

Answer 1

Answer:

$\\ \frac{ - 16}{9} - \frac{5}{12} + \frac{7}{18} = \\ \\ = lcm = 3 \times 3 \times 2 \times 2 = 36 \\ \\ = \frac{ - 16}{9} \times \frac{4}{4} = \frac{ - 64}{36} \\ = \frac{ - 5}{12} \times \frac{3}{3} = \frac{ -15}{36} \\ = \frac{7}{18} \times \frac{2}{2} = \frac{14}{36} \\ \\ = \frac{ - 64 - 15 + 14}{36} = \frac{ - 79 + 14}{36} \\ \\ = \frac{ - 65}{36}$
