Question

You are reading a book 560 pages long.You have read about 11/20 or the book.What percent of the book have you read?

Answer 1

If you've x/100 of the book, you've read x%

So for what x is
\[ \frac{11}{20} = \frac{x}{100} \]

Answer 2

Hint:
\[ \frac{11}{20} = \frac{ 5 \times 11}{5 \times 20} \]

Answer 3

For example, suppose you've read 1/2 of the book, what percentage is that?

Well, it's x% where \( 1/2 = x/100 \).
\[ \frac{1}{2} = \frac{50 \times 1}{50 \times 2} = \frac{50}{100} \]

Hence 1/2 is 50% of the book.
