Solve

Step-by-step explanation:

We have to find the value of  \frac{-5}{7} + \frac{1}{12} + \frac{3}{4} + \frac{-1}{3} + \frac{10}{7} + -\frac{1}{6}

= \frac{-5}{7} + \frac{1}{12} + \frac{3}{4} + \frac{-1}{3} + \frac{10}{7} -\frac{1}{6}

First, we will solve the fraction with same denominators.

= \frac{-5}{7} + \frac{10}{7}  + \frac{1}{12} + \frac{3}{4} + \frac{-1}{3}-\frac{1}{6}

= \frac{-5 + 10 }{7} + \frac{1}{12} + \frac{3}{4} + \frac{-1}{3}-\frac{1}{6}

= \frac{5 }{7} + \frac{1}{12} + \frac{3}{4} + \frac{-1}{3}-\frac{1}{6}

We have to find the LCM of the denominators.

First let us solve the last two fractions.

LCM of 3 and 6 is 6.

= \frac{5 }{7} + \frac{1}{12} + \frac{3}{4} + \frac{-2}{6}-\frac{1}{6}

= \frac{5 }{7} + \frac{1}{12} + \frac{3}{4} + \frac{-2 - 1}{6}

= \frac{5 }{7} + \frac{1}{12} + \frac{3}{4} + \frac{-3}{6}

The LCM of 12, 4 and 6 is 12.

So, now

= \frac{5 }{7} + \frac{1}{12} + \frac{9}{12} - \frac{6}{12}

= \frac{5 }{7} + \frac{1 + 9 - 6}{12}

= \frac{5 }{7} + \frac{4}{12}

\frac{4}{12} can also be written as \frac{1}{3}.

= \frac{5 }{7} + \frac{1}{3}

LCM of 7 and 3 is 21.

Now,

= \frac{15 }{21} + \frac{7}{21}

= \frac{22}{21}

So the answer is \frac{22}{21}, which can also written as 1\frac{1}{21}.

So the correct option is c.
