Step-by-Step Solution

To solve this problem, let's convert the decimal number 0.66 to a fraction and then reduce it:

Step 1: Convert the decimal to a fraction.
The decimal 0.66 can be expressed as 66100\frac{66}{100} because it has two decimal places. This places the 66 over 100.

Step 2: Simplify the fraction 66100\frac{66}{100}.
To simplify, we need to find the greatest common divisor (GCD) of the numerator 66 and the denominator 100.

The prime factorization of 66: 66=2×3×1166 = 2 \times 3 \times 11
The prime factorization of 100: 100=2×2×5×5100 = 2 \times 2 \times 5 \times 5

The common factor between them is 2. Thus, the GCD is 2.
Now, divide both the numerator and the denominator by the GCD, which is 2.

66100=66÷2100÷2=3350\frac{66}{100} = \frac{66 \div 2}{100 \div 2} = \frac{33}{50}

Therefore, the fraction 3350\frac{33}{50} is the simplest form of 0.66.

The final, reduced fraction is: 3350\frac{33}{50}.

Answer

3350 \frac{33}{50}
