Question

48分之35乘(77分之36+55分之72)怎么巧算？能巧算吗？急啊，求你们快点顺便说一下过程

Answer 1

35/48(36/77+72/55)
先将括号里面的和提取出11分子36即36/11
再将括号外的分子35乘到括号里面去，就去掉括号里面的分母了。外面就变成36/48＝3/4
括号里面变成5+2*7＝19
所以原式＝（3/4）*19＝57/4

Answer 2

35/48x(36/77+72/55)=35/48x[(36x55+72x77）/(77x55)]
=35/48x[36(55+2x77)/7x5x11x11]
=1/4x[3x(55+2x77)/11x11]
=3x(55+2x77)/4x11x11
=33x(5+14)/44x11
=57/44
