Math Problem Statement

Write 0. 32 overbar as a fraction in simplest form.

Solution

To convert 0.320.\overline{32} (which means the decimal 0.323232...0.323232... repeating) into a fraction, we can follow these steps:

Step 1: Set up an equation

Let x=0.32x = 0.\overline{32}, meaning: x=0.32323232x = 0.32323232\ldots

Step 2: Eliminate the repeating decimal

To eliminate the repeating part, multiply both sides of the equation by 100 (since the repeating part is two digits long): 100x=32.32323232100x = 32.32323232\ldots

Step 3: Subtract the two equations

Now subtract the original equation from the new equation: 100xx=32.323232320.32323232100x - x = 32.32323232\ldots - 0.32323232\ldots 99x=3299x = 32

Step 4: Solve for xx

Now, divide both sides by 99: x=3299x = \frac{32}{99}

Step 5: Simplify the fraction

The fraction 3299\frac{32}{99} is already in its simplest form, since 32 and 99 have no common factors other than 1.

So, the fraction equivalent to 0.320.\overline{32} is: 3299\boxed{\frac{32}{99}}
