How to Add 1-Digit and 2-Digit Decimals Step by Step
FAQs on Adding Decimals for Class 4: 1-Digit Plus 2-Digit Worksheet
1. How do you add decimals with different digits, like a 1-digit and 2-digit decimal?
To add decimals with a different number of digits, you must first align the numbers by their decimal points. This ensures that you are adding the correct place values together (tenths to tenths, hundredths to hundredths).
Follow these steps:
- Step 1: Write the numbers one below the other, making sure the decimal points are in a straight vertical line.
- Step 2: Add one or more zeros to the end of the number with fewer decimal places so that both numbers have the same length. For example, to add 4.5 and 2.35, you would write 4.5 as 4.50.
- Step 3: Add the numbers from right to left, just like you would with whole numbers.
- Step 4: Place the decimal point in your answer directly below the other decimal points.
2. What are the steps to add decimals for Class 4?
Adding decimals in Class 4 involves a few simple steps that focus on place value. This worksheet provides excellent decimal addition practice to master this skill.
The key steps are:
- Line Up: Write the numbers vertically so the decimal points are aligned.
- Add Zeros: Add placeholder zeros at the end of numbers if needed, so they have an equal number of decimal places.
- Add: Start adding the columns from the far right and move left, just like with regular addition. Regroup if necessary.
- Place Decimal: Bring the decimal point straight down into your answer.
3. Why is place value important in adding decimals?
Place value is crucial in decimal addition because it ensures that you are combining parts of the same size. When you correctly align the decimal points, you make sure you are adding tenths to tenths and hundredths to hundredths.
For example:
- In the number 5.28, the 2 is in the tenths place and the 8 is in the hundredths place.
- Incorrectly aligning place values would be like adding pennies and dimes as if they were the same, leading to a wrong answer.
- This place value of decimals worksheet for Grade 4 helps reinforce this concept.
