Answer:
-3.75
Explanation:
In order to find the rational number between -4 and -7/2, we need to follow two simple steps. (Same as finding the average).
1. Add the two numbers together
2. Divide the sum of them by 2
And there! You get the midpoint! :D
Now, let's solve... -4 - 7/2 = -7.5 <-- Adding them together
-7.5 / 2 = -3.75 <-- Dividing the sum by two and getting the result
After adding the numbers together and dividing them, we got -3.75 as the midpoint!
