Answer 1

answer - 115/441

sum = 2/3+(-3/7)

=14-9/21

= 5/21

difference = 2/3-(-3/7)

=2/3+3/7

=14+9/21

= 23/21

multiplication = 5/21×23/21

= 115/441

Answer 2

Answer:

115/441

Step-by-step explanation:

First we need to find the sum,

so, sum= 2/3 +(-3/7)

= 14/21 - 9/21

= 5/21

Next, we need to find the difference

so, difference = 2/3 - (-3/7)

= 14/21 + 9/21

= 23/21

Last, Multiplication = Sum ×Difference

Multiplication = 5/21 × 23/21

= 115/441

Solution = 115/441
