a = 0.66...
b = 0.73
c = 7/8
Step-by-step explanation:
The first two numbers, 0.73 and 0.667, are near the point that is halfway between 0.6 and 0.8. That halfway point is 0.7. The value 0.667 will be below (left) of the halfway point, so is point <em>a</em>. The value 0.73 will be above (right) of the halfway point, so is point <em>b</em>. The remaining value, 7/8, must be point <em>c</em>.
