依据题意列式计算如下:
6/7÷[8/11×（3/4+1/6）]
=6/7×11/8÷（9/12+2/12）
=6/7×11/8×12/11
=9/7
=1又7分之2
6/7÷[8/11×（3/4+1/6）]
=6/7×11/8÷（9/12+2/12）
=6/7×11/8×12/11
=9/7
=1又7分之2

6/7÷[8/11×（3/4+1/6）]
=6/7÷[8/11×（9/12+2/12）]
=6/7÷[8/11×11/12]
=6/7÷2/3
=6/7×3/2=9/7=1又2/7
=6/7÷[8/11×（9/12+2/12）]
=6/7÷[8/11×11/12]
=6/7÷2/3
=6/7×3/2=9/7=1又2/7
