Hey zaktheflamme! You can first transform the decimal number into a fraction. For example with 0.08: $$ 0.08 = \frac{8}{100} $$ We then find the greatest common factor: PGCD(8, 100) = 4. We divide the tow terms in the fraction by the GCF: $$ \frac{8}{100} = \frac{\frac{8}{4}}{\frac{100}{4}} = \frac{2}{25} $$ Here's an AlloProf sheet to help you with it:
