Question

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

Answer 1

$\:$

Answer:

Thrice the rational number -8/3= 3×(-8/3)= -8

Let the number that is to be subtracted from -8 to get 5/2 be 'a'.

Now, according to the given condition,

-8-a= 5/2

= -a= 5/2+8

Taking the LCM of 2 and 1,

-a= 5+8×2/2

-a= 5+16/2

-a= 21/2

a= -21/2

Therefore, -21/2 is to be subtracted from thrice the rational number -8/3 to get 5/2.
