Use the digits 1-9 to create 3 equivalent ratios. Each digit can only be used once. _:_=_ _:_=_ _:_ _

3 equivalent ratios are:

Explanation:

Given:

Number to be chosen = 1 to 9

Each digit can be used once.

We have to find three equivalent ratios.

So,

Considering the simplified ratio to be

Then, the three equivalent ratios are:

when simplified gives

when simplified gives

Therefore, 3 equivalent ratios are:

the answer is two. hope this !
