Decimals - Tenths

1 whole unit can be split into 10 equal parts. Each part is one tenth

Or we can show the same thing this way:

One (1) whole unit	Split into ten equal parts (tenths)		Each part is one tenth

Numbers with place value

When we write numbers with tenths using decimals we use a decimal point and the tenths place to the right of this decimal point.The tenth place is immediately right of the decimal point.

9/10 = .9	.	9	We read this number as nine tenths
