Question

5/6+(4/5-3/4)×12/7的竖式计算怎样计算？

Answer 1

5/6+(4/5-3/4)×12/7
=5/6+(16/20-15/20)×12/7
=5/6+1/20×12/7
=5/6+3/35
=175/210+18/210
=193/210

Answer 2

5/6+(4/5-3/4)×12/7
=5/6×4/5×12/7-5/6×3/4×12/7
=4x2/7-5/2x3/7
=8/7-15/14
=16/14-15/14
=1/14

Answer 3

你这个题目肯定是写错了，这都是分数的，加减法和乘法的呀，分数计算怎么可能用竖式的呢？你肯定应该是写用梯等式。只有这样才是这样一步一步的等下来。这个怎么能列竖式不可能列竖式的呀？

Answer 4

4/5-3/4=0.05

Answer 5

5/6+(4/5-3/4)×12/7
=5/6+(16/20-15/20)×12/7
=5/6+1/20×12/7
=5/6+3/35
=175/210+18/210
=193/210
