Answer:

He read 1/3 of the book on the second day

He didn't finish the book in two days.

Step-by-step explanation:

Lets find 3/5 of 5/9

If we said, find 3/5 of x, the answer would be 3/5x.

3/5*x = 3/5x

In the same way, $\frac{3}{5} *\frac{5}{9} = \frac{15}{45} = \frac{1}{3}$

He read 1/3 of the book on the second day

Does 5/9 + 1/3 equal to 1?

1/3 = 3/9

5/9 + 3/9 = 8/9

He didn't finish the book in two days.

Hope this helps :)

Have a nice day!
