Answer:
145.309
Step-by-step explanation:
So we want to find the midpoint of the two number: 145.809 and 144.809, what we want to do it to find the difference between the two numbers and then divide it by 2 so we can find the halfway point:
145.809 - 144.809 = 1
^ So from this, we just have to add half of 1 or 0.5 to the smaller number:
144.809 + 0.5 = 145.309
