Выполните деление 3/4:9, 2/5:10, 11/15:22, 4/7:2, 2 1/7:15, 1 7/9:8, 4 1/2:6, 5 1/7:7

Решение: при делении дробей используем правило (x/y)/(n/m)=x/y*m/n=(x*m)/(y*n)3/4:9=(4/4)/(9/1)=(3*1)/(4*9)=3/36=1/122/5:10=(2/6)/(10/1)=(2*1)/(5*10)=2/50=1/2511/15:22(11/15)/(22/1)=(11*1)/(15*22)=11/330=1/304/7:2=(4/7)/(2/1)=(4*1)/(7*2)=4/14=2/72 1/7:15=(15/7)/(15/1)=(15*1)/(7*15)=1/71 7/9:8=(16/9)/(8/1)=(16*1)/(9*8)=2/04 1/2:6=(9/2)/(6/1)=(9*1)/(2*6)=9/12=3/45 1/7:7=(36/7)/(7/1)=(36*1)/(7*7)=36/49
