by their difference.​

Answer 1

Question:

Divide the sum of -1/12and -4/9 by their difference…

Answer:

$\frac{ (\frac{ - 1}{12} + \frac{ - 4}{9} )}{ (\frac{ - 1}{12} - \frac{ - 4}{9} )}$

L.C.M. of 12 and 9 = 36

$\frac{ \frac{ - 1 \times 3}{12 \times 3} + \frac{ - 4 \times 4}{9 \times 4} }{ \frac{ - 1 \times 3}{12 \times 3} - \frac{ - 4 \times 4}{9 \times 4} }$

$\frac{ \frac{ - 3}{36} + \frac{ - 16}{36} }{ \frac{ - 3}{36} - \frac{ - 16}{6} }$

$\frac{ \frac{ - 3 + ( - 16)}{36} }{ \frac{ - 3 - ( - 16)}{36} }$

$\frac{ \frac{ - 3 - 16}{36} }{ \frac{ - 3 + 16}{36} }$

$\frac{ \frac{ - 19}{36} }{ \frac{ - 13}{36} }$
