Answer:
2.5

Explanation:

Given the following expression:

ab-0.5b

And given these values of "a" and "b":

$a=1\\ b =5$

You need to follow these steps in order to evaluate it:

1. You must substitute the values of "a" and "b" into the expression provided:

ab-0.5b=(1)(5)-0.5(5)

2. Now, you need to solve the multiplications:

=5-2.5

3. Finally, you must solve the subtraction. Then:

=2.5
