In this blog post, you can learn how to compare two decimals.
Step by step guide to compare decimals
A decimal is a fraction written in a special form. For example, instead of writing \(\frac{1}{2}\) you can write \(0.5\).
For comparing decimals:
- Compare each digit of two decimals in the same place value.
- Start from left. Compare hundreds, tens, ones, tenth, hundredth, etc.
- To compare numbers, use these symbols: Equal to \(=\), Less than \(<\), Greater than \(>\) Greater than or equal \(\geq\), Less than or equal \(\leq\)
Example 1:
Compare \(0.40\) and \(0.04\).
Answer:
\(0.40\) is greater than \(0.04\), because the tenth place of \(0.40\) is \(4\), but the tenth place of \(0.04\) is zero. Then: \(0.40 \ > \ 0.04 \)
Example 2:
Compare \(0.0912\) and \(0.912\).
Answer:
\(0.912\) is greater than \(0.0912\), because the tenth place of \(0.912\) is \(9\), but the tenth place of \(0.0912\) is zero. Then: \(0.0912 \ < \ 0.912 \)
Example 3:
Compare \(0.20\) and \(0.02\).
Answer:
0.20 is greater than \(0.02\), because the tenth place of \(0.20\) is \(2\), but the tenth place of \(0.02\) is zero. Then: \(0.20>0.02 \)
Example 4:
Compare \(0.0210\) and \(0.110\).
Answer:
\(0.0.110\) is greater than \(0.0210\), because the tenth place of \(0.110\) is \(1\), but the tenth place of \(0.0210\) is zero. Then: \(0.0210<0.110\)
