Clay is reading a book that is 30 pages long. He read 2/3 of the book on Saturday and 1/2 of the remainder on Wednesday. How many pages did Clay have left to read?
This question is a two part question, so let's start solving the first part.
First, let's find 2/3 of the book that is 30 pages long. This isn't too hard to find:
2/3 * 30 = 20
Now that we know he read 20 pages, we know that there are 10 pages left to read. Because Clay read 1/2 of the remainder of the book on Wednesday, we know that he read five pages.
Now we can add 20 and 5 to get 25 pages. This is the number of pages that Clay has read.
So, we know that the answer is equal to:
30 - 25 = 5
So, he has 5 pages left to read.
