Select three ratios that are equivalent to 11:1
zavuch27 [327]
To solve this problem you must apply the proccedure shown below:

 1. You have the following ratio given in the problem above: 

 11:1

 2. You can rewrite that ratio as below:

 11/1=11

 3. Then, to find three equivalent ratios, you only need to multiply the numerator (11) and the denominator (11) by the sam number. Therefore, you have:

 11x2/1x2=22/2=11
 11x3/1x3=33/3=11
 11x4/1x4=44/4=11

 Therefore, as you can see, the answer is:

 22:2
 33:3
 44:4
