Math Problem Statement

For each number, determine if it can be written as a fraction. Then state the reason.

Solution

Let's analyze the table provided in the image. The goal is to determine if each number can be written as a fraction and explain the reason based on whether the number is a terminating decimal, a repeating decimal, or neither. Here's the solution:

  1. 0.92

    • Can this be written as a fraction? Yes
    • Reason: This is a terminating decimal because it ends after two decimal places.
  2. 0.\overline{6} (0.666...)

    • Can this be written as a fraction? Yes
    • Reason: This is a repeating decimal because the digit 6 repeats infinitely. It equals 23\frac{2}{3}.
  3. 0.222...

    • Can this be written as a fraction? Yes
    • Reason: This is a repeating decimal because the digit 2 repeats infinitely. It equals 29\frac{2}{9}.
  4. 0.257963...

    • Can this be written as a fraction? No
    • Reason: This is a decimal that neither terminates nor repeats, as there is no discernible repeating pattern or end.

Would you like a detailed explanation for any of these, or have further questions? 😊

Tip:

To convert a repeating decimal to a fraction, use algebra: Let xx equal the repeating decimal, multiply xx to shift the repeating part, then subtract and solve for xx.
