=(24+8/247)×19/8
=24×19/8+8/247×19/8
=57+1/13
12又285分之45×4.75÷115
=(12+285分之45)×19/4÷115
=(12×19/4+285分之45×19/4)÷115
=(57+×3/19×19/4)÷115

=1/2+1/460
24又247分之8×2.375+12又285分之45×4.75÷115-195分之167
=57+1/13+1/2+1/460-195分之167
=57+1/13-195分之167+1/2+1/460
=56+43/195+1/2+1/460
=56+1/2+(43*23*4)/(23*4*13*3*5)+39/(23*4*13*3*5)
=56+1/2+3995/(23*4*13*3*5)
=56+1/2+791//(23*4*13*3)
=56+2585/3558
亲哦~问题是这样的~24又247分之8×2.375+12又285分之45×4.75---------------------------------------------------------(分数线)115-195分之167亲帮我解答一下嘛~谢谢啦~
