Answer:
442
Step-by-step explanation:
These are easy, we just have to average the corresponding coordinates.
First we do a few one dimension ones, the midpoint of points on a number line:
1. 9 & 6

2. -2 & 7

3. -3 & -13

For the rest of these we're in 2D, the Cartesian plane.
4. (0,0), (9,3)

5. (-2,1), (3,6)

6. (-3, 14), (10, -4)

Answer:
22/25, 89/100,899/1000,9/10,9/8
Step-by-step explanation:
They all factor into 100 or can be put in a fraction out of 100 except 9/8 but since it’s improper unlike the others , you can already tell it’s the biggest 9/8= 1 1/8
The answer is 14.2.... hope this helps
