Answer 2

Solution:

Let's calculate the total fraction of the book that Kolya read over two days.

1. First Day: - Kolya read two tenths (2/10) of the book.

2. Second Day: - Kolya read one-tenth (1/10) more than the previous day, which means he read (2/10 + 1/10) = 3/10 of the book.

Total Fraction Read:

Kolya read 2/10 + 3/10 = 5/10 of the book over the two days.

So, Kolya read 5/10 (or 1/2) of the book over the two days.
