pls answer i will mark you brainliest

Answer 1

Answer:

Given thrice the rational number -5/3

3 * -5/3 = -5

Let the number be x.

-5 - x = 1/2

-x = 1/2 +5

x = - ( 1/2 + 5)

x = - (1 + 10 / 2)

x = (-11/2 )

x = (-11/2 ) should be subtracted from thrice the rational number -5/3 to get 1/2

Verification :-

-5 + 11 /2

-10 + 11 /2

x = 1/2
