Divide the sum of 13/5 and -12/7 by two product of -13/7 and 1/2 .❓❓

Solution:--

sum of 13/5 and -12/7

= 13/5 + (-12/7)

= (13×7-12×5)/35

= (91-60)/35

= (31/35

And,

product of -13/7 and 1/2

= -13/7 × 1/2

= -13/14

a/c to question ..

31/35 ÷ -13/14

Answer 2

Answer:

Step-by-step explanation

the product = $\frac{-13}{7}  * \frac{1}{2} =\frac{-13*1}{7*2} =\frac{-13}{14}$ and two product equals to $2*\frac{-13}{14}$=$\frac{-13}{7}$.  the sum = $\frac{13}{5} +\frac{-12}{7} =\frac{91-60}{35} +\frac{31}{35}$. the last  step = $\frac{31}{35}: \frac{-13}{7}  =\frac{-31}{35} *\frac{7}{13} =\frac{-31}{65}$
