Answer:
10:1:5
Step-by-step explanation:
Let's mark names as their first letter:
Amy=A
Bill=B
Cara=C
The ratio should be like this A:B:C
A=10*B
C=A/2 or A*1/2
If it is the simplest, then Bill have to score 1 point.
10*1=10 (Amy's score)
10/2=5 (Cara's score)
If it is Amy:Bill:Cara then the ratio of points score by them is 10:1:5
