Writing numbers in decimal format provides us we a quick way to write a fraction and mixed number value that are based on powers of ten. If a number has a decimal point the number to the left are whole numbers and the numbers to the right indicate values that are less than one. The first digit to the right of the decimal point indicates the number of tenths. The second trailing digit indicates the number of hundredths. If a third digit trails them, it is the value of thousandths. Place value notation is a positional system where each successive value is different a power of ten. In the decimal (base ten) system each place value differs by a power of ten. Standard place value jumps can be display as ten to an exponential power. As you go up in place value, the exponent to the power of ten grows. As you move to the right of the decimal point you move into decimal country. Decimals are noted as powers of ten with a negative value.

These worksheets explain how to identify the value of a number in a specified place within a decimal and convert fractions into decimals. You well learn how to not the exact value of each place. We will also work up to transferring these values into other forms of notation like fractions and percentages. We will expand to indicate values on a rang of thousands t thousandths. This is a big section make sure to take the quiz when you feel you have a good handle on what was covered.
