which is not a true proportion?

Answer: The answer is C
Step-by-step explanation:
If you look at the other ratios you can see a common pattern.
The top and the bottom have been multiplied by the same number.
Example: 1/2 and 7/14. Both 1 and 2 were multiplied by seven to make a true proportion.
So answer C was the only one that wasn’t multiplied by the same number.
