Question

Divide the sum of 13/5 and minus 12/7 by the product of - 31/7 and 1/ -2.

Answer 1

Answer:

2/5 is the answer.

Step-by-step explanation:

$Sum \ of \ \frac{13}{5} \ and \ \frac{-12}{7} \\ \\= \frac{13}{5} + \frac{-12}{7} \\\\ = \frac{(91-60)}{35} \\\\=\frac{31}{35} \\\\ Product \ of \ \frac{-31}{7} \ and \ \frac{1}{-2} \\\\=(\frac{-31}{7})(\frac{1}{-2} ) \\\\=\frac{31}{14} \\\\ Dividing \ sum \ of \ \frac{13}{5} \ and \ \frac{-12}{7} \ by \ product \ of \ \frac{-31}{7} \ and \ \frac{1}{-2} \\\\= \frac{\frac{31}{35}}{\frac{31}{14}} \\\\ = (\frac{31}{35})(\frac{14}{31}) \\\\=\frac{2}{5}$

Answer 2

Answer:

Here is your answer frnd...
