Answer 1

Respuesta:

• $\frac{9}{4}* \frac{16}{27} =\frac{9*4*4}{4*9*3}=\frac{4}{3}$
• $5*\frac{9}{25}=\frac{5*9}{5*5}=\frac{9}{5}$
• $\frac{12}{15} *\frac{25}{36}= \frac{3*4*5*5}{3*5*4*9}=\frac{5}{9}$
• $\frac{12}{15}:\frac{4}{25}=\frac{12}{15}*\frac{25}{4}=\frac{3*4*5*5}{3*5*4}=5$
• $\frac{18}{5}* \frac{1}{9}* \frac{5}{11}= \frac{2*9*5}{5*9*11}=\frac{2}{11}$
• $\frac{4}{9}: \frac{8}{3}= \frac{4}{9}*\frac{3}{8}=\frac{4*3}{3*3*4*2}=\frac{1}{6}$
