Answer: 18/25 chapters / hour
Step-by-step explanation:
<u>Concept:</u>
Here, we need to know the idea of unit rate.
A unit rate is a rate with 1 in the denominator.
In simple words, the unit rate is something per one thing. For example, when you go to a store, you bought a book that is priced at $10. In actually meaning, it is $10 per book, or $10/book.
<u>Solve:</u>
<em>Given formula</em>
Unit rate = Number of chapters / Hours
<em>Substitute the value into the formula</em>
Unit rate = (3/5) / (5/6)
<em>Convert to multiplication by taking the reciprocal of the divisor</em>
Unit rate = (3/5) · (6/5)
<em />
<em>Numerator times numerator / denominator times denominator</em>
Unit rate = (3 × 6) / (5 × 5)
Unit rate = 18 / 25 chapter / hour
