What is the middle number between 2 and 2.5?

2.25

Step-by-step explanation:

To find the middle number—of any 2 numbers—is to add them together, then to divide it by 2. We do this because when you add them toher and divide them by 2, you get the exact middle number that follows.

So, we can do the same for 2 and 2.5.

2+2.5=4.5

Now we divide it by 2 to get the middle number.

4.5 divided by 2 = 2.25
