Homework Review

Rational Numbers A rational number is: Any number that can be written as a ratio (or fraction) Rational numbers include fractions, terminating and repeating decimals, ratios, and percents.

Switching between Fractions and Decimals It is important to be able to express rational numbers as both fractions and decimals. Ex: ½ = 0.5 We will use the TOGGLE button on the calculator to help us convert between the two.

Equivalent Rational Numbers Until the 21st century, stock prices were recorded as fractions. Today, those prices are shown as decimals. For example a gain of $2.25 per share used to be recorded as 2 ¼. How can a loss of 5/8 per share be recorded as a decimal?

Try a few on your own.

Compare and Order Decimals When comparing decimals, write one number under the other with the place values line up. Compare the digits in each place-value position, moving right.

Comparing Decimals

Ordering Decimals Put the following in order from least to greatest. Ex 1: 0.04, 0.027, 0.2, 0.098 Ex 2: -0.5763, -0.58, -0.5367, -0.0875
