Step-by-step solution

The problem

0.66

  1. Write the digits over 100. 0.66 has 2 decimal places, so put the digits (without the point) over 1 followed by 2 zeros.

    = \textcolor{#0b5c56}{\frac{66}{100}}

  2. Simplify. Write both as prime factors:\begin{aligned} 66 &= 2 \times 3 \times 11 \\[6pt] 100 &= 2^{2} \times 5^{2} \end{aligned}The only factor they share is 2, so the greatest common factor (GCF) is 2. Divide the top and bottom by 2.

    = \frac{66 \div 2}{100 \div 2} = \textcolor{#0b5c56}{\frac{33}{50}}

All the working together

\begin{aligned} &0.66 \\[8pt] &= \frac{66}{100} && \textcolor{#5b6660}{\textsf{over 100}} \\[8pt] &= \frac{66 \div 2}{100 \div 2} && \textcolor{#5b6660}{\textsf{simplify}} \\[8pt] &= \textcolor{#0b5c56}{\frac{33}{50}}\end{aligned}
