please mark me as brainlist and give me some points
Here is your answer:
To find,
( \frac{-13}{5} + \frac{12}{7} ) \div ( \frac{-31}{7} \times \frac{-1}{2})(
5
−13
+
7
12
)÷(
7
−31
×
2
−1
)
Solution:
⇒ ( \frac{-13}{5} + \frac{12}{7} ) \div ( \frac{-31}{7} \times \frac{-1}{2}) = ( \frac{-91}{35}+ \frac{60}{35}) \div ( \frac{-31 \times -1}{7\times 2})(
5
−13
+
7
12
)÷(
7
−31
×
2
−1
)=(
35
−91
+
35
60
)÷(
7×2
−31×−1
)
⇒ ( \frac{(-91) +60}{35} ) \div ( \frac{31}{14})(
35
(−91)+60
)÷(
14
31
)
⇒ ( \frac{-31}{35}) \div ( \frac{31}{14})(
35
−31
)÷(
14
31
)
⇒ ( \frac{-31}{35}) \times ( \frac{14}{31}) = \frac{-14}{35} = \frac{-2}{5}(
35
−31
)×(
31
14
)=
35
−14
=
5
−2
Therefore the answer is -2/5 .
