A.) (2, 10), add -6 to -2 to give you 4 units. Then add 4 to the midpoint(-2, and 7), and you end up with 2 and 3. Then just add 3 to seven and you have the coordinates of (2, 10), hope this helps!
It is where the numerator and the denominator (or both) contain a fraction.
0.3km=300m
300m:500m
(/100)
3:5
3+5=8
0.3km= 3/8
500m= 5/8
