In Naming decimals, the decimal point and the place value of the last digit are significant. Naming the integer part of the decimal is similar to naming whole numbers. With naming the fractional part, there are additional steps to be considered.
Note:
If the last digit of the fractional part is zero (0), proceed to the next nonzero digit to the left and consider its place value and name it.
Separate the integer part from the fractional part.
`20` integer part
`*` decimal point
`13` fractional part
Name the integer part normally as a whole number.
`20` = twenty
Replace the decimal point with "and".
`*` = and
Name the fractional part as a whole number and use the place value name for the last digit of the decimal after.
`13` - thirteen
`3` is the hundredth's digit of `20.13`.
Use hundredths.
Combining the names;
`20.13` = twenty and thirteen hundredths
Therefore, `20.13` is twenty and thirteen hundredths in words.
Separate the integer part from the fractional part.
`1` integer part
`*` decimal point
`20` fractional part
`1` = one
Replace the decimal point with "and".
`*` = and
Since the last digit of the fractional part is 0, use the next nonzero digit which is 2.
`2` = fractional part
Name the fractional part as a whole number and use the place value for the last digit of the decimal after.
`2` = two
`2` is the tenth's digit of `1.20`.
Use tenths.
Combining the names;
`1.20` = one and two tenths
Therefore, `1.20` is one and two tenths in words.
