Question

Do these ratios form a proportion?

628 units : 346 months

994 units : 400 months

Answer 1

To determine if the ratios form a proportion, we need to check if the two ratios are equivalent.

We can do this by cross-multiplying:

628 units * 400 months = 251,200
994 units * 346 months = 343,124

Since the cross products are not equal, the ratios do not form a proportion.
