From 86 books to 150 books. An increase of 64 books.

(150 - 86) / 86 = 64 / 86 = 0.744 * 100% = 74.40% or 74% increase

150 / 86 = 1.744 * 100% = 174.40%

86 is the basis. It is 100%

If the problem asks for the value of the percentage increase and the rate is given 74.4% of 86. Then 86 * 74.4% = 64. You just add 64 to 86 to get the new total of books which is 150.

China has a population of approximately 1,322,000,000 people. Express this number in scientific notation.
Rasek [7]
In scientific notation, you must move the "invisible decimal point" until there is a one-digit number, sometimes followed by a decimal of more numbers. Then, how ever many digits you had to move it is the exponent to the number 10.
Example:
1200.
120.0
12.00
1.200
Since the decimal had to move 3 places, the scientific notation of this is:
1.2 • 10^3

In this question, the decimal must move 9 places left before resulting in 1.322.
So the answer, in scientific notation, is 1.322 • 10^9.
