Question

计算8/11×［(3/4－4/9)÷5/3］÷7/4

Answer 1

这是一道分数四则混合运算题，按照运算顺序，要先算括号里面的。然后按照运算顺序进行计算。
8/11*【(3/4-4/9）/5/3】/7/4
=8/11*【(27/36-16/36）/5/3】/7/4
=8/11*【11/36*3/5】/7/4
=8/11*11/60/7/4
=8/11*11/60*4/7
8/105

Answer 2

这是一道分数四则运算题。
=8/11x〔(3/4-4/9)X3/5〕x4/7
=8/11X4/7x(9/20-12/45)
=32/77X(81/180-48/180)
=32/77x33/180
=8/7×3/45
=8/7x1/15
=8/105

Answer 3

8/11×[(3/4-4/9)÷5/3]÷7/4
=8/11×[27/36-16/36)×3/5]×4/7
=8/11×(11/36×3/5)×4/7
=8/11×11/36×3/5×4/7
=2/9×3/5×4/7
=2/15×4/7
=8/105

Answer 4

8/11×［(3/4－4/9)÷5/3］÷7/4
=8/11×（3/4×3/5-4/9×3/5）×4/7
=8×9×4/（11×4×5）-8×4×4/（11×3×5）
=72/55-128/165
=216/165-128/165
=88/165
=8/55

Answer 5

8/11×［(3/4－4/9)÷5/3］÷7/4
=8/11×（3/4-4/9）×3/5×4/7
=8/11×（27/36-16/36）×3/5x4/7
=8/11×3/5x4/7x11/36
=8/105
