UNIT 12: INTRODUCTION TO DECIMALS

Decimals are numbers that contain a "DECIMAL POINT", like:
 1.5 2.8 0.2 3.14 66.66

The number to the left of the decimal point is an ordinary whole number. The number to the right of the decimal is called the "tenths" digit and tells you the number of tenths (1/10's) that are added to the whole number to the left of the decimal point. So...
 1.5 is the same as the mixed number 2.8 is the same as the mixed number .2 is the same as the mixed number

If there are 2 numbers to the right of the decimal point then both numbers to the right of the decimal point are the number of "hundredths" (1/100's) to be added to the whole number, so.....

 3.14 is the same as the mixed number 66.66 is the same as the mixed number
