问题描述:
[0.75-﹙7∕3-10∕9)÷4]÷[﹙3∕2+8∕3﹚÷5∕2-5∕6]的结果.
答
[0.75-﹙7∕3-10∕9)÷4]÷[﹙3∕2+8∕3﹚÷5∕2-5∕6]
=(3/4-11/36)÷[(25/6)×2/5-5/6]
=4/9÷(5/3-5/6)
=4/9×6/5
=8/15
答
8/15
答
[0.75-﹙7∕3-10∕9)÷4]÷[﹙3∕2+8∕3﹚÷5∕2-5∕6]=[3/4 -11/9 *1/4]÷[(3∕2+8∕3﹚*2/5-5∕6]=[27/36 -11/36]÷[3/5 +16/15 -5/6]=16/36 ÷[36/60+64/60-50/60]=4/9 ÷5/6=4/9 *6/5=8/15
