Question

divide the sum of 13 upon 5 and minus 12 upon 7 by the product of minus 31 upon 7 and 1 upon minus 2​

Answer 1

Answer:

Answer is −2/5

Step-by-step explanation:

Explanation :

product of −31/7 and −1/2=−31/7×−12=−31×−1/7×2=31/14.

sum of −13/5 and 12/7=(−13/5)+(12/7)

=(−13×7/5×7)+(12×5/7×5)

=(−91/35)+(60/35)

=(1/35)(−91+60)=−31/35.

Dividing the sum of -13/5 and 12/7 by the product of -31/7 and -1/2

⟹−31/35/31/14=−31×14/35×31=−14/35=−2/5

Answer 2

ANSWER

2/5

EXPLANATION

the sum of 13/5 & -12/7 is = (13/5) + (-12/7)

=13/5 -12/7

=91-60/35

=31/35

the product of the-31/7 & 1/-2 is=(-31/7) ÷ (1/-2)

= -31/7 × 1/-2

= 31/14

the division of this is=31/35 ÷ 31/14

=31/35 × 14/31

=2/5
