There are an infinite number of equivalent ratios. To get an equivalent ratio, you must multiply or divide the numerator AND denominator by the same number. For example, 1/8 is also 2/16 because I multiplied the top and bottom by 2.
\(1/8\) is the same thing as \(1:8\) So if you do the equation \(1/8\) or \(1:8\)\(*2\)\(=2:18\) because \(1*2=2\) and \(8*2=16\) So the answer is also known as \(2/16\) You have to multiply top and bottom by \(2\).
