Answer:
1. is 7 to 1 and
2. is 3 to 6
Step-by-step explanation:
You get number one's answer by finding to difference between 13 to 7 which Is six. so now you start at 1 and add 6 which would be 7 and would give you your answer of 7 to 1.
You get number two's answer by finding the ratio given which is 1 black square to 2 Grey squares. Since it mentions to triple it you multiply both numbers by 3. which would give you 3 to 6. You know that this is right because it is equivalent to 1/2 which was what the first ratio was.
