Question

Are the ratios 2:1 and 9:5 equivalent?

Answer 1

Answer:

no

Step-by-step explanation:

if we put the ratios as fractions, we would get 2/1, or just 2, and 1 4/5. these are not equivalent, so the ratios are not equivalent either.

Answer 2

Answer:

No.

Step-by-step explanation:

2:1 has multiple equivalents, for example:

2:1

4:2

6:3

5:10

...

The 1st number will always be double of the 2nd number,

2 is double of 1

4 is double of 2

6 is double of 3

...

9 is not double of 5.
