​

Answer 1

\begin{gathered}A) \\ \\ \frac{4}{10}= \frac{4:2}{10:2}= \frac{2}{5} \\ \\ B) \\ \\ \frac{8}{12} = \frac{8:4}{12:4} = \frac{2}{3} \\ \\ C) \\ \\ \frac{28}{36} = \frac{28:4}{36:4} = \frac{7}{9} \\ \\ D) \\ \\ \frac{40}{32} = \frac{40:8}{32:8} = \frac{5}{4} \\ \\ E) \\ \\ \frac{54}{42}= \frac{54:6}{42:6} = \frac{9}{7} \\ \\ F) \\ \\ \frac{36}{100} = \frac{36:4}{100:4} = \frac{9}{25} \\ \\ ESPERO~TER~AJUDADO~E~BONS~ESTUDOS!\end{gathered}
