LESSON 12: DECIMAL NUMBERS
Our number system revolves around place value, specifically base 10.
How do the place values relate to one another?
We name decimals based on the last digit of the decimal
USE WORDS TO WRITE EACH NUMBER. THEN WRITE THE DECIMAL NUMBER AS A REDUCED FRACTION
a. 0.325 b. 5.08
Order these numbers from least to greatest.
0.34, 0.306, 0.09, 0.8
TO REWRITE FRACTIONS AS DECIMALS, USE LONG DIVISION.
Express 3 as a decimal number.
CONVERTING DECIMALS TO PERCENTS
Multiply by 100/Shift the decimal point 2 places to the right
Ex: Convert 1.03 as a percent
CONVERTING PERCENTS TO DECIMALS
