which is not in the form of a ratio

Answer:
b is the answer
Step-by-step explanation:
We're going to start with the first one
60m/1 HR
The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2. So it would be 120 : 2
The next one only has 1 number and that is 1
It is not a form of a ratio because you can't turn a one digit number into a ratio. A ratio has two digits for each side for an example:
This can be turned into a ratio / 19 to 8
This cannot be turned into a ratio/ 8
So there you have it letter b is your answer.
