Answer 2

Answer:

-11/2

Step-by-step explanation:

Question :

The number that needs to subtracted from the thrice of the rational number -8/3 to get 5/2

Solution :

Let the required number which must be subtracted  from thrice the rational  number -8/3 to get 5/2 be x

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

According to the given condition,

$x - (-8) = \frac{5}{2} \\\\=> x + 8 = \frac{5}{2 } \\\\=> x = \frac{5}{2} - 8 \\\\=> x = \frac{5 - 16}{2} \\\\=> x = \frac{-11}{2}$

So, the number subtracted from thrice the rational  number -8/3 to get 5/2 is

$\boxed {\mathbf {\frac{-11}{2} }}$
