Math Problem Statement

Use the repeating decimal 8.̸̅ to answer the following questions: Part A: How can it be represented as a mixed number? Part B: How can it be represented as an improper fraction?

Solution

Let's analyze the problem in the image.

Part A: Mixed Number Representation

The repeating decimal given is 8.38.\overline{3}.

This can be expressed as a mixed number by recognizing that the repeating decimal 0.30.\overline{3} is equivalent to the fraction 13\frac{1}{3}.

So, 8.3=8+13=8138.\overline{3} = 8 + \frac{1}{3} = 8 \frac{1}{3}.

Correct Answer for Part A: 8138 \frac{1}{3}

Part B: Improper Fraction Representation

Next, convert the mixed number 8138 \frac{1}{3} into an improper fraction.

To do this: 8×3+1=24+1=258 \times 3 + 1 = 24 + 1 = 25 So, 813=2538 \frac{1}{3} = \frac{25}{3}.

Correct Answer for Part B: 253\frac{25}{3}

Summary

  • Part A: 8138 \frac{1}{3} (Correct choice is the first option).
  • Part B: 253\frac{25}{3} (Correct choice is the first option).
