Question

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

Answer 1

Answer:

58/45

Step-by-step explanation:

let that number be x

so, x + -8/9 = 2/5

when 8/9 will go that side of equal to sign , it will become positive

so , x = 2/5 + 8/9

so LCM = 45

x = 18/45 + 40/45

x = 58/45

so the number is 58/45

-----------------------

⇒ Let us take the unknown no. as '$x$'

⇒ $\frac{-8}{9} + x = \frac{2}{5}$

⇒ $x = \frac{2}{5} + \frac{8}{9}$

⇒  $x = \frac{18+40}{45}$

⇒$x = \frac{58}{45}$
