Question

what should be subtracted from -4/9 so as to get 5/12

Answer 1

Let the required value be x.
By guven condition,
-4/9 - x = 5/12
x = -4/9 - 5/12
x = [-4 (4) - 5 (3)]÷ 36
x = (-16-15)÷ 36
x = -31/36

Hope it helps !! ;-)

Answer 2

Let the required value be x.

-4/9 - x = 5/12

x = -4/9 - 5/12

x = [-4 (4) - 5 (3)]= 36

x = (-16-15)= 36

x = -31/36
