(567+354*566)/(567*345+222)=?
(567+354*566)/(567*345+222)=?
(567+354*566)/(567*345+222)=?
567+345*566/567*345+222
=(345+345*566+222)/(567*345+222)
=(345*567+222)/(567*345+222)
=1
(567+345*566)/(567*345+222)
=(567+345*566)/[(566+1)*345+222]
=(567+345*566)/(566*345+345+222)
=(567+345*566)/(566*345+567)
=1
①根据楼主的问题我用科学计算器算的的标准答案是
(567+354*566)=200931
567*345+222=15837
200931÷15837=12.68744080318242
②可能是楼主打错了题目,前面的两个回答都是把题目改了求的(把354改成了345),
可能正确的题目为
(567+345*566)/(567*345+222)

这样正好把式子分解的来求、 祝学业有成

如果分子上是345而不是354的话,答案是1,你没写错吧?
