99.38-99.38

Video Solution

Solution Steps

00:00 Determine if the decimal point placement is correct?
00:03 We'll use long subtraction to find the decimal point placement
00:06 In long subtraction, decimal points must be aligned one above the other
00:11 In our exercise, the decimal points are aligned one above the other
00:21 And secondly, let's look at the number we want to subtract
00:25 The numbers appear to be equal, therefore the exercise is valid
00:30 And this is the solution to the question

Step-by-Step Solution

To effectively assess the problem, we should confirm if the decimal points in the subtraction of two identical numbers, 99.3899.3899.38 - 99.38, are aligned correctly.

Step 1: The numbers involved in the subtraction are 99.3899.38 and 99.3899.38, both having the same number of digits before and after the decimal point.

Step 2: Check the alignment of the decimal points in the subtraction setup. In properly written subtraction involving decimals, the decimal points must align vertically to ensure correct digit placement.

Step 3: The setup displays the numbers:

  • 99.3899.38
  • 99.3899.38

Each digit before and after the decimal is in perfect vertical alignment, confirming correct decimal point alignment.

Conclusion: The exercise is correctly written in terms of decimal alignment.

The correct answer to the problem is True.
