Question

which number should be added to -8/9 to get 2/5​

Answer 1

Answer:

Let's find the required number.

Explanation:

Let the required number be x.

x + 2/5 = - 3/7

x = -3/7 - 2/5

x = [-15 - 14] / 35

x = -29/35

Thus, the required number is -29/35 that should be added to 2/5 to get -3/7.

Answer 2

Let the number be e

So, - 3/5+e=2/5

e=2/5-(-3/5)

e=2/5+3/5 (as ‘- and - = +’)

e= (2+3)/5

e=5/5

Which when simplified gives

e=1..
