1/6 book over 2/3 hour as a unit rate should be written as: B.1/4 book/hour.
In Mathematics and Euclidean Geometry, a unit rate refers to the quantity of material that is equivalent to a single unit of product or quantity.
Based on the information provided above, we can logically deduce that the total part of books is 1/6 and the total part of hours is 2/3. In this context, an equivalent unit rate can be calculated by using the following formula;
Unit rate = Total part of books/Total part of hours
Unit rate = 1/6 ÷ 2/3
Unit rate = 1/6 × 3/2
Unit rate = 3/12
Unit rate = 1/4 book per hour.
