How to Add One-Digit Decimals Easily for Grade 4 Students
FAQs on Class 4 Maths Worksheet: Adding Decimals (1 Digit)
1. How do you add decimals for Class 4?
To add decimals in Class 4, you must line up the decimal points vertically before adding the numbers column by column. This method ensures that digits with the same place value are added together correctly.
Here are the simple steps to follow:
- Step 1: Write down the numbers, one under the other, making sure to align the decimal points.
- Step 2: Add zeros as placeholders if the numbers have a different number of decimal places.
- Step 3: Add each column of digits, starting from the rightmost side.
- Step 4: Place the decimal point in the answer directly below the other decimal points.
2. What is the easiest way to add decimals with one digit?
The easiest way to add decimals with one digit after the point is to stack the numbers vertically and align their decimal points. This simple trick ensures you add tenths to tenths and ones to ones without any confusion.
For example, to add 4.2 + 3.5:
- Line them up:
4.2
+ 3.5 - Add the numbers from right to left: 2 + 5 = 7, and 4 + 3 = 7.
- Place the decimal point in the answer: 7.7.
3. Why is place value important when adding decimals?
Place value is crucial when adding decimals because it ensures that you are combining digits of the same value. Correctly aligning the decimal points guarantees that you add tenths to tenths, ones to ones, and so on, which prevents incorrect answers.
For instance, without respecting place value, adding 12.3 and 4.56 could be done incorrectly. Aligning the decimal point ensures the 3 (tenths) is added to the 5 (tenths), not the 6 (hundredths).
