Question

What should be subtracted from thrice the rational number -5/3 to get 1/2?​

Answer 1

The number to be subtracted = -11/2

Explanation:

(3*rational number)-x=1/2

The rational number given = -5/3

Then thrice the rational number

= 3*rational number

= 3*(-5/3)

= -5

(3*rational number)-x=1/2

-5-x= 1/2

-5- 1/2= x

-11/2= x

The number to be subtracted = -11/2
