Sally has read one-third of her book. She finishes the book by reading the same amount each night for 5 nights. Part A. What fraction of the book does she read each of the 5 nights

2/15

Step-by-step explanation:

Given that she have already read one-third of the book.

The fraction f of the book that will remain is;

f = 1 - 1/3 = 2/3

Then she finishes the book by reading the same amount each night for 5 nights

That implies she reads the remaining 2/3 of the book at equal rates for 5 nights.

Let x represent the fraction rate read per night;

5x = 2/3

Divide both sides by 5

x = 2/3 * 1/5

x = 2/15

Therefore, she reads 2/15 of the book every night for 5 nights.
