The decimal point of a number separates the whole part of the number from the fractional part of the number. It is located between the units column and the tenths column of every number. A decimal place is one of the digits after the decimal point: The first decimal place is the first digit, which is the tenths digit The second decimal place is the second digit, which is the hundredths digit The third decimal place is the third digit, which is the thousandths digit etc. When showing or rounding to a number of decimal places there will be that number of digits after the decimal place. eg the number 5.671 has three decimal places as there are three digits after the decimal point and the second decimal place, for example, contains the digit 7.
