Express thirty-nine and five tenths in standard form.

We’re working with the number thirty-nine and five tenths. To write this in standard form, we’ll need to take the words and turn them into numerals. Thirty-nine written in numerals is a three and a nine. In this case, the phrase “and” tells us where to put the decimal point.

“Thirty-nine and” here means three nine decimal point. Five tenths tells us to put our five in the tens place. And the tens place is the first place to the right of the decimal point.

When you put those altogether, we see the standard form of thirty-nine and five tenths. It is 39.5.
