0.25k + 1.5 − k − 3.5
combining like terms with rational coefficients

-  0. 75 k - 2 .

Step-by-step explanation:

Given  : 0.25k + 1.5 − k − 3.5

To find : Combining like terms with rational coefficients.

Solution : We have given 0.25k + 1.5 − k − 3.5.

On combining like term

0.25 k - k + 1.5 - 3.5.

-  0. 75 k - 2 .

Therefore, -  0. 75 k - 2 .
