Place Value with Decimals Division by 10

When converting from decimals to fractions, how do we determine the denominator?

• It's the place value farthest to the right of the decimal. "Tenths" would be 10, "Hundredths" would be 100, "Thousandths" would be 1000 and so on.

• It's the original number without the decimal

• It's always 10.

• The denominator is the bottom number of a fraction.
