julyap $1) \frac{1*5}{6*6} = \frac{5}{36} \\ \\ 2) \frac{4*5}{8*2} = \frac{5}{2*2} = \frac{5}{4} =1.25 \\ \\ 3) 2* \frac{5}{6} * \frac{4}{15} = \frac{5}{3} * \frac{4}{15} = \frac{1*4}{1*5} = \frac{4}{5} =0.8 \\ \\ 4)3* \frac{2}{3} * \frac{1}{2} =2* \frac{1}{2} =1 \\ \\ 5)9- \frac{5}{9} =8 \frac{9}{9} - \frac{5}{9} =8 \frac{4}{9}$

$6)5* \frac{4}{9} +7* \frac{3}{5} = \frac{49}{9} + \frac{38}{5} = \\ \\ =5 \frac{4}{9} +7 \frac{1}{5} =5 \frac{20}{45} +7 \frac{9}{45} =12 \frac{29}{45}$
