The first figure to the right of the unit is called 

 the first decimal place; the second figure, the sec- 

 ond decimal place, etc. We see in the above that 

 the number of decimal places in a decimal equals 

 the number of ciphers to the right of the figure 1 in 

 the denominator of the equivalent fraction. This 

 fact kept in mind will be of much assistance in read- 

 ing and writing decimals.
