Answer 2

Answer:

$-0.49$

Step-by-step explanation:

• As per the data given in the question, we need to divide the sum of $\frac{-13}{15}$ and $\frac{12}{7}$ by the product of $\frac{-31}{7}$ and $\frac{-1}{2}$

• Sum of $\frac{-13}{15}$ and $\frac{12}{7}$

• L.C.M of $15,7=105$

$\frac{-13}{15}+\frac{12}{7}$

$=\frac{-91+180}{105}$

$=\frac{-89}{105}$

• Product of $\frac{-31}{7}$ and $\frac{-1}{2}$

$\frac{-31}{7} \times\frac{-1}{2}$$=\frac{31}{14}$

Now,

$=\frac{-89}{105}\div \frac{12}{7}$

$=\frac{-89}{105}\times \frac{7}{12}$

$=-0.49$

Hence, the answer is $-0.49$.
