Question

6/7 + 3/14 + (- 5/21 )​

Answer 1

☆ANSWER:

☞Given:

$\frac{6}{7} + \frac{3}{14} + (\frac{ - 5}{21})$

☞A.T.Q:

We first find the LCM of the denominators.

So, the LCM of 7, 14 and 21 is 42

=> $\frac{6 \times6 }{7 \times 6} + \frac{3 \times 3}{14 \times 3} + ( \frac{ - 5 \times 2}{21 \times 2})$

=> $\frac{36 + 9 + ( - 10)}{42}$

=> $\frac{35}{42} \: or \: \frac{5}{6}$ (simplified)

∴ The answer is $\frac{5}{6}$
