Lesson Excerpt:
Do you remember learning about place values for whole numbers? Now let’s look at place values for decimals. To start with, all we’re going to do is put a decimal point in the whole number 791524. Like this: 791524.62713
The place values for the whole number are quite easy:
7 = hundred thousands
9 = ten thousands
1= thousands
5 = hundreds
2 = tens
4 = ones or units
But what about the decimals? Decimals are just another way of writing fractions.
