Question

Why would it be be appropriate to express a ratio of 7 to 9 but not a ratio 7 to 14?

Answer 1

Answer:

A 7:9 ratio is simplified as much as it can.

While a 7:14 ratio can be reduced to 1:2.

Answer 2

Answer:

A ratio of 7:14 reduces to 1/2.

Step-by-step explanation:

A ratio of 7:9 cannot be reduced because both 7 and 9 are prime and only divisible by 1. The ratio 7:14 has a common divisor of 7 so it reduces to 1:2
