Question 2.
Larry spends half of his workday teaching piano lessons. If he sees 6 students, each for the same amount of time, what fraction of his workday is spent with each student?
Answer:
The fraction of his workday is spent with each student is \(\frac{1}{12}\).
Explanation:
Given that Larry spends half of his workday teaching piano lessons. And the duration of piano lessons is \(\frac{1}{2}\). As he sees 6 students, each for the same amount of time. So,
the duration of teaching each student = duration of teaching piano lessons ÷ Number of students.
= \(\frac{1}{2}\) ÷ 6
= \(\frac{1}{2}\) × 6
= \(\frac{1}{12}\).
So the fraction of his workday is spent with each student is \(\frac{1}{12}\).

Teams of four are competing in a quarter-mile relay race. Each runner must run the same exact distance. What is the distance each teammate runs?
Answer:
Each person will run \(\frac{1}{16}\) miles.
Explanation:
Given that there are teams of four are competing in a quarter-mile relay race and each runner must run the same exact distance, so the distance each teammate runs is,
so each person will run = the total distance ÷ number of persons in a team
= \(\frac{1}{4}\) ÷ 4
= \(\frac{1}{4}\) × \(\frac{1}{4}\)
= \(\frac{1}{16}\).
so each person will run \(\frac{1}{16}\) miles.
Question 4.
Solomon has read \(\frac{1}{3}\) of his book. He finishes the book by reading the same amount each night for 5 nights.
a. What fraction of the book does he read each of the 5 nights?
Answer:
Solomon reads \(\frac{2}{15}\) of the book each night.
Explanation:
Given that Solomon has read \(\frac{1}{3}\) of his book, so 1 – \(\frac{1}{3}\) which is \(\frac{2}{3}\) of the book is left to be read. And we have that, in 5 nights Solomon reads \(\frac{2}{3}\) of the book. So for 1 night he will read \(\frac{2}{3}\) × \(\frac{1}{5}\) which is \(\frac{2}{15}\) of the book.
b. If he reads 14 pages on each of the 5 nights, how long is the book?
Answer:
The total number of pages in the book is 105.
Explanation:
Let the total number of books be X, as he reads 14 pages on each of the 1 night. So he reads 14 × 5 which is 70 pages in 5 nights. So \(\frac{2}{3}\)of the total pages is 70, which is
\(\frac{2}{3}\) X = 70, on solving we will get
X = 105.
So the total number of pages in the book is 105.
