Question

what no. should be subtracted from -2/3 to get -1/6

Answer 1

Let x should be subtracted
so
-2/3 - x = -1/6
-2/3 + 1/6 = x
Taking their lcm and solving further
(-4+1)/6 = x
-3/6 = x
So x=-1/2

Answer 2

Answer:

Let the number be x.

Acc to the que,

-2/3 - x = -1/6

-2/3 + 1/6 = x

-4+1/6 = x

-3/6 =x

x = -3/6

x = -1/2

Hence, the required number is -1/2
