Question

|+3 8/11|-|-27/10|-|+19/11|+|-9/5| 初一数学 要过程~~

Answer 1

=41/11-27/10-19/11+9/5(根据绝对值规则去掉绝对值)
=41/11-19/11-27/10+18/10(调整各个分数位置，并且统一分母)
=22/11-(27/10-18/10)
=22/11-9/10
=220/110-99/110(统一分母)
=121/110
=11/10(分子分母简化)
（不知道你那个3 8/11是不是3又8/11的意思）

Answer 2

|+3 8/11|-|-27/10|-|+19/11|+|-9/5|
=3+8/11-2-7/10-1-9/11+9/5
=1-1/11-7/10+18/10
=10/11+11/10
=(100+121)/110
=221/110
