Subtracting Decimals with Ease
Subtracting decimals can be a daunting task, especially when dealing with numbers that have multiple digits after the decimal point. However, with the right approach, it can be a breeze. In this post, we will break down the simple steps to subtract 1.633 by 1.2.
Step 1: Line Up the Decimals
The first step in subtracting decimals is to line up the numbers correctly. This means ensuring that the decimal points are aligned vertically. In our case, we have:
1.633 -1.200
Note that we add a zero to the end of the second number to ensure that both numbers have the same number of digits after the decimal point.
📝 Note: When subtracting decimals, it's essential to line up the numbers correctly to avoid errors.
Step 2: Subtract the Numbers
Now that our numbers are lined up, we can proceed to subtract the numbers. Starting from the rightmost digit, we subtract each digit of the second number from the corresponding digit of the first number.
1.633
-1.200
0.433
In this case, we subtract 3 from 3, 3 from 2, and 2 from 1, carrying over the 1 to the next column.
📝 Note: When subtracting decimals, we follow the same rules as subtracting whole numbers, carrying over digits as necessary.
Step 3: Check Your Answer
The final step is to check our answer to ensure that it makes sense. In this case, our answer is 0.433. We can check our answer by plugging it back into the original equation:
1.633 - 1.2 =?
If our answer is correct, the equation should hold true.
📝 Note: Always check your answer to ensure that it is correct and makes sense in the context of the problem.
To make it easier, you can also use a table to visualize the subtraction:
| Numbers | Subtraction |
|---|---|
| 1.633 | -1.200 |
| 0.433 | |
By following these simple steps, you can easily subtract 1.633 by 1.2 and get the correct answer of 0.433.
To summarize, subtracting decimals is a straightforward process that requires lining up the numbers correctly, subtracting the numbers, and checking your answer. By following these steps, you can confidently tackle decimal subtraction problems with ease.
