What calculation is modeled on the number line?

A. [tex]2 \frac{2}{3} + 2 \frac{1}{3} = 5[/tex]

B. [tex]2 \frac{2}{3} + 5 = 7 \frac{2}{3}[/tex]

C. [tex]5 - 2 \frac{2}{3} = 2 \frac{2}{3}[/tex]

D. [tex]5 - 2 \frac{1}{3} = 2[/tex]

Certainly! Let's break down the calculation that is modeled on the number line step-by-step.

Step 1: Understanding the given numbers

We need to work with the numbers 5 and [tex]\(2 \frac{1}{3}\)[/tex].

Step 2: Understanding [tex]\(2 \frac{1}{3}\)[/tex]

Identify what [tex]\(2 \frac{1}{3}\)[/tex] represents. It is a mixed number that can be converted to an improper fraction for easier calculation, but for simplicity, we can also treat it as a mixed number directly.

Step 3: Subtract [tex]\(2 \frac{1}{3}\)[/tex] from 5

To perform the subtraction, you could first convert [tex]\(2 \frac{1}{3}\)[/tex] to an improper fraction, but it's not necessary here. Instead, you can think of it as subtracting two whole numbers and then taking care of the fractional part.

So think of subtracting 2 from 5 first:

[tex]\[5 - 2 = 3\][/tex]

Step 4: Handle the fractional part

Now subtract the fractional part:

[tex]\[3 - \frac{1}{3}\][/tex]

Converting 3 to a fraction with the same denominator as [tex]\(\frac{1}{3}\)[/tex], we get:

[tex]\[3 = \frac{9}{3}\][/tex]

So the subtraction becomes:

[tex]\[ \frac{9}{3} - \frac{1}{3} = \frac{8}{3} \][/tex]

Step 5: Simplify the result

Convert [tex]\(\frac{8}{3}\)[/tex] back to a mixed number:

[tex]\[\frac{8}{3} = 2 \frac{2}{3}\][/tex]

So the final result of [tex]\(5 - 2 \frac{1}{3}\)[/tex] is:

[tex]\[5 - 2 \frac{1}{3} = 2 \frac{2}{3}\][/tex]

Therefore, the calculation modeled on the number line shows that subtracting [tex]\(2 \frac{1}{3}\)[/tex] from 5 results in [tex]\(2 \frac{2}{3}\)[/tex].

[tex]\[\boxed{2 \frac{2}{3}}\][/tex]

This explains the result.
