Question

9分之4除以2又5分之一减百分之25乘11分之5加36分之一乘11分之7我要简算

不要简算了

Answer 1

4/9÷2又1/5-25%x5/11+1/36x7/11
=4/9÷11/5-1/4x5/11+1/36x7/11
=4/9x5/11-1/4x5/11+1/36x7/11
=5/11x(4/9-1/4)+1/36x7/11
=5/11x(16/36-9/36)+1/36x7/11
=5/11x7/36+1/36x7/11
=7/36x1/11x(5+1)
=7/36x1/11x6
=7/66

Answer 2

3又2分之一减7分之3减2分之1
的差=7/2-(3/7-1/2)=7/2-3/7+1/2=8/2-3/7=4-3/7=
3又7分之4；
11分之8加11分之3减11分之2的差加7分之5=8/11+(3/11-2/11)+5/7=8/11+1/11+5/7=9/11+5/7=63/77+55/77=118/77
