Math Problem Statement
Identify the decimal labeled with the letter A on the scale below.
Solution
In the image, you are working on a problem that requires you to identify the decimal represented by the letter A on a number line between 0 and 1. You have entered 0.9, which seems to have been marked incorrect.
Looking closely at the number line:
- The number line appears evenly divided between 0 and 1, with five segments.
- This means the segments represent increments of 0.2 each.
Let's break it down:
- The first tick after 0 represents 0.2.
- The second tick represents 0.4.
- The third tick represents 0.6.
- The fourth tick represents 0.8.
- The final tick (right at 1) represents 1.
The letter A seems to be at the second tick mark, which corresponds to 0.4, not 0.9.
So, the correct answer for A would be 0.4.
Would you like further details, or do you have any questions? Here are five questions to expand on this:
- What other values could A represent if the intervals were different?
- How would this number line change if it spanned from 0 to 2?
- What is the significance of correctly identifying decimals on a number line?
- How can you use this concept to approximate irrational numbers on a number line?
- How can you apply this knowledge to real-world measurements?
Tip: Always count the intervals between numbers on a number line before determining where a point falls!
