Answer 2

Calculation of the Remaining Unread Portion of the Book

To determine the remaining unread portion of the book, we need to subtract the portions that Tanya has already read from the total.

On the first day, Tanya read 1/4 of the book, and on the second day, she read 3/5 of the book.

To find the remaining unread portion, we subtract the sum of the portions Tanya has read from the total portion of the book:

Remaining unread portion = Total portion - (Portion read on the first day + Portion read on the second day)

Let's calculate it step by step:

1. Total portion of the book: 1 (whole book)

2. Portion read on the first day: 1/4

3. Portion read on the second day: 3/5

Now, let's calculate the remaining unread portion:

Remaining unread portion = 1 - (1/4 + 3/5)

To simplify the calculation, we need to find a common denominator for 4 and 5, which is 20:

Remaining unread portion = 1 - (5/20 + 12/20)

Adding the fractions:

Remaining unread portion = 1 - (17/20)

Subtracting the fractions:

Remaining unread portion = 3/20

Therefore, Tanya has 3/20 of the book left to read.
