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.
No.
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.
