Question

Find the sum of the following
7/9 + (– 10/18) + (– 7/27)

Answer 1

Bonjour!

$= > \frac{7}{9} - \frac{10}{18} - \frac{7}{27} \\ \\ = > \frac{42}{54} - \frac{30}{54} - \frac{14}{54} \\ \\ = > \frac{42 - 30 - 14}{54} \\ \\ = > - \frac{2}{54} \\ \\ = > - \frac{1}{27}$

Hope this helps...:)

$= \frac{7}{9} + \frac{ - 10}{18} + \frac{ - 7}{27} \\ \\ = \frac{42 - 30 - 14}{54} \\ \\ = - \frac{ 2}{54} \\ \\ = - \frac{1}{27}$
