Question

4 multiple choice 5 points which fraction shows the unit rate that is equal to the ratio 18 : 2? \\(\frac{1}{9}\\) \\(\frac{2}{18}\\) \\(\frac{18}{2}\\) \\(\frac{9}{1}\\) d a c b clear my selection

Explanation:

Step1: Understand unit rate

A unit rate is a ratio that compares a quantity to 1 unit of another quantity. For the ratio \(18:2\), we need to simplify it to have a denominator of 1.

Step2: Simplify the ratio

The ratio \(18:2\) can be written as the fraction \(\frac{18}{2}\). To find the unit rate, we divide 18 by 2: \(\frac{18}{2} = 9\), which is equivalent to \(\frac{9}{1}\) (since 9 divided by 1 is 9, and this shows the rate per 1 unit).

Answer:

D. \(\frac{9}{1}\)
