Question

What number shoul be added to -5/6 to get 2/3​

Answer 1

Let it be x

ATQ

$\\ \sf\longmapsto x+\dfrac{-5}{6}=\dfrac{2}{3}$

$\\ \sf\longmapsto \dfrac{6x-5}{6}=\dfrac{2}{3}$

$\\ \sf\longmapsto 3(6x-5)=6(2)$

$\\ \sf\longmapsto 18x-15=12$

$\\ \sf\longmapsto 18x=12+15=27$

$\\ \sf\longmapsto x=\dfrac{27}{18}$

$\\ \sf\longmapsto x=\dfrac{3}{2}$

Answer:

9/6 or 3/2

Step-by-step explanation:
