(-3分之1)-6分之5-6分之1 等于几?-3.92+6.47-8.56+4.28 等于几?|-6|-(-1)-|-5+3|等于几?

问题描述:

(-3分之1)-6分之5-6分之1 等于几?-3.92+6.47-8.56+4.28 等于几?|-6|-(-1)-|-5+3|等于几?
还有(1.7)-|-4.3|+|-1.7|+(-6.

(-3分之1)-6分之5-6分之1=-1/3-(5/6+1/6)=-1/3-1=-4/3-3.92+6.47-8.56+4.28 =-3.92-8.56+(6.47+4.28)=-12.48+10.75=-1.73|-6|-(-1)-|-5+3|=6+1-2=5(1.7)-|-4.3|+|-1.7|+(-6.8)=1.7-4.3+1.7-6.8=3.4-11.1...
