As we have a base ten system, the first number to the right of the period represents the given number (''n'') out of ten (^''n'''''/'''₁₀), known as tenths. this can be used to find the value of any place, by multiplying the place to its left by ¹/₁₀ and substituting the given number for 1. Using the tenths example, this would be, 1 x ¹/₁₀, to find the value of 0.1 . A simpler way of thinking about this that as we move right, each place gets ten times smaller.

When writing decimals without a whole number, a 0 is generally placed on the left side of the period to signify that the number is both a decimal and that there are no whole number components.

When writing decimals without a whole number, a 0 is generally placed on the left side of the period to signify that the number is both a decimal and that there are no whole number components. A dash over the final digit indicates that the decimal continues infinitely, or without ending. Such cases are referred to as repeating decimals.
