Determine whether the exercise is written correctly in relation to the position of the decimal point:
The problem requires us to verify if the subtraction exercise of the decimal numbers is written correctly, focusing on the position of the decimal points.
Step-by-step:
Step 1: Identify the given numbers, and .
Step 2: Align these numbers by their decimal points for proper subtraction.
Upon alignment, the numbers are:
.
To correctly align them for subtraction, we can rewrite as to match the number of decimal places:
The decimal points are aligned correctly in both numbers, confirming that the exercise is set up accurately regarding the position of the decimal point.
Thus, the answer to the problem is Yes.
Yes.
Determine whether the exercise is written correctly in relation to the position of the decimal point:
Because decimal numbers have different place values! When you line up from the right, you might be subtracting tenths from hundredths, which gives wrong results. Always align the decimal points first.
It's very helpful but not always required. Adding zeros like changing 3.2 to 3.20 makes the subtraction clearer and reduces mistakes. It's a good habit to develop!
Every whole number has an invisible decimal point after it! For example, 5 is really 5.0 or 5.00. Add the decimal point and zeros as needed for alignment.
Check that all decimal points line up in a straight vertical line. If they don't, your setup needs adjustment before you start subtracting.
Yes, but vertical alignment makes it much easier to keep track of place values and avoid errors, especially with borrowing in subtraction problems.
