Final answer:
d) 5:7. To determine which ratio is not equivalent to the others, simplify each ratio and compare them. The ratio 5:7 is not equivalent to the others.
Step-by-step explanation:
To determine which ratio is not equivalent to the others, we need to simplify the ratios and compare them.
Let's simplify each ratio:
- a) 2:3 can be simplified to 2/3
- b) 6:9 can be simplified to 2/3
- c) 8:12 can be simplified to 2/3
- d) 5:7 cannot be simplified further
Comparing the simplified ratios, we see that a), b), and c) are all equivalent to 2/3, while d) is not equivalent to the others. Therefore, the answer is d) 5:7.
