How to Compare Decimal Numbers in Grade 4 Maths?
FAQs on Comparing Decimals: Class 4 Maths Worksheet with Answers
1. How to compare decimal numbers in Grade 4?
To compare decimal numbers, you should follow a simple step-by-step method. This process helps in correctly identifying which decimal is greater, less than, or equal to another.
- Step 1: Compare the whole number parts (the digits to the left of the decimal point). The number with the larger whole number part is greater.
- Step 2: If the whole number parts are the same, compare the digits in the tenths place (the first digit after the decimal point).
- Step 3: If the tenths are also equal, move to the hundredths place and compare those digits.
For example, to compare 5.72 and 5.69, you see the whole numbers (5) are the same. Then, you compare the tenths place: 7 is greater than 6, so 5.72 > 5.69.
2. What is the rule for comparing decimals?
The main rule for comparing decimals is to compare the digits in the same place value, moving from left to right. Start with the whole number part and then proceed to the decimal part, one digit at a time.
- Always align the decimal points before comparing.
- Compare the digits in the tenths place first.
- If the tenths are equal, compare the digits in the hundredths place.
- The first place value where the digits differ determines which number is larger.
3. How do you write greater than and less than with decimals?
You use the standard mathematical symbols to show the relationship between two decimal numbers. These symbols are a key part of any decimal comparison exercise.
- The 'greater than' symbol (>) points away from the larger number. For example, 0.8 > 0.3 because 8 tenths is greater than 3 tenths.
- The 'less than' symbol (<) points towards the smaller number. For example, 4.15 < 4.51 because 15 hundredths is less than 51 hundredths.
- The 'equal to' symbol (=) is used when two decimals represent the same value, like 0.5 = 0.50.

10. What is the easiest way to compare two decimals with different numbers of digits?
The easiest way to compare decimals with different lengths is to make them the same length by adding zeros to the end. Adding zeros to the right of the last digit in a decimal does not change its value.
- Example: To compare 0.7 and 0.65.
- Step 1: Add a zero to 0.7 to make it 0.70. This helps in direct comparison as both now have two decimal places.
- Step 2: Now, compare 0.70 and 0.65. It's clear that 70 is greater than 65.
- Step 3: Therefore, 0.7 > 0.65.
