Question

-6又5分之1-2分之1-1+4又5分之1-4.5+3又3分之1

Answer 1

原式=(-6又1/5)-(1/2)-1+(4又1/5)-4.5+(3又1/3)
=(-6又1/5)-(1/2)-1+(4又1/5)-(4又1/2)+(3又1/3)
=[(-6又1/5)+(4又1/5)]+[(-1/2)+(-4又1/2)]-1+(3又1/3)
=[-(6又1/5-4又1/5)]+[-(1/2+4又1/2)]+(-1)+(3又1/3)
=-2+(-5)+(-1)+(3又1/3)
=-8+(3又1/3)
=-(8-3又1/3)
=-(24/3-10/3)
=-14/3

可以有过程吗？

追答

把带分数和小数化为假分数相加减就ok啦。
