Question

What should be subtracted from thrice the rational number -8/3 to get 5/2?​

Answer 1

Let the number be 'a'

'a' should be subtracted from thrice the rational number -8/3 to obtain 5/2

3(-8/3) - a = 5/2

-8- a = 5/2

a = 5/2+8

a = 21/2

The number is 21/2

Answer 2

Answer:

Step-by-step explanation:

let required number be x.

Now, x should be subtracted from thrice(-8/3) and answer should be 5/2

so, 3*(-8/3)-x=5/2

so, -8-x=5/2

so, -16-2x=5

so, -2x=-11

so 2x=11

so x=11/2
