Answer 1

Question:

Simplyify 5/36+(-7/8)+6/-72+(-3/-12)

Solution:

$\large \frac{5}{36} + ( - \frac{7}{8} ) + (\frac{6}{ - 72} ) + ( \frac{\cancel {- } \: 3}{\cancel{ - }\:12} )$

$\large \implies \: \frac{5}{36} - \frac{7}{8} + ( \frac{ - 6}{ 72} ) + ( \frac{3}{12} )$

$\large \implies \: \frac{5}{36} - \frac{7}{8} - \frac{6}{72} + \frac{3}{12}$

Taking LCM

$\implies \: \frac{5(2)-7(9)-6(1)+3(6)}{72}$

$\implies \: \frac{(10 - 63 - 6 + 18)}{72} \\ \\ \implies \: \frac{28 - 69}{72} \\ \\ \implies \: \frac{ - 41}{72}$

Hence, -41/72 is the answer.

Hope it helps you.
