Worked Example 1
Tenths vs. Hundredths
Compare 0.7 and 0.65.
- 1Write 0.7 as 0.70 so both have hundredths.
- 2Both have 0 ones. Tenths: 7 is greater than 6.
- 3So 0.7 is greater.
Answer: 0.7 > 0.65

What Is Benchmark MA.4.NSO.1.5?
Students plot, order, and compare decimals up to the hundredths using number lines and place value, explain their reasoning, and use <, >, or =.
Compare the ones first, then the tenths, then the hundredths. Writing a zero at the end (0.7 = 0.70) can make two decimals easier to compare, because it doesn't change the value.

Worked Example 2
Order Three Decimals
Order 2.5, 2.05, and 2.45 from least to greatest.
- 1All have 2 ones. Compare the tenths: 5, 0, and 4.
- 20 tenths is least, then 4 tenths, then 5 tenths.
Answer: 2.05, 2.45, 2.5
Common Mistakes to Watch For
Thinking a longer decimal is greater
Wrong:0.45 > 0.5
0.5 is 5 tenths, which is 0.50. 0.45 < 0.5.
Ignoring the ones place
Wrong:0.9 > 1.2 because 9 > 2
1.2 has 1 one and 0.9 has 0 ones. 0.9 < 1.2.
Helpful Math Tip
Use money: 0.7 is 70 cents and 0.65 is 65 cents. Which would you rather have?
