Thousandths.The big ideaThe last word names the last place. Zeros hold places. Compare from the left.
How it works
The last word names the last place. 0.684 is 684 thousandths.
Zeros hold places. 3.370 and 3.37 are equal.
Compare from the left, place by place.
Example 1: Compare
- Compare 0.684 and 0.113: greater, less or equal?
- Start with the tenths: 6 and 1.
- 6 tenths is more than 1 tenth.
- So the answer is > Greater than.
Example 2: Write it
- Write as a decimal: six and seven hundred ninety-two thousandths
- The word 'and' marks the point.
- Seven hundred ninety-two thousandths is .792.
- So the answer is 6.792.
Example 3: A trailing zero
- Compare 3.370 and 3.37: greater, less or equal?
- 3.370 has an extra zero at the end.
- That zero doesn't change the value.
- So the answer is = Equal to.
