Yes, when converting a decimal to a fraction the denominator of the fraction will always be a power of ten. This is because our decimal system breaks apart the decimal number into tenths [katex] (\\cfrac{1}{10}), [/katex] hundredths [katex] (\\cfrac{1}{100}), [/katex] thousandths [katex] (\\cfrac{1}{1000}), [/katex] etc.
