问题描述:

计算(-4又7/8)-(-5又1/2)+(-4又1/4)-(+3又1/8)
我自己算的哦=(-4 7/8)-(+3 1/8)-(5 1/2)+(-4 1/4) =(-8)+5 1/2-4 1/4 =6 3/4

(-4又7/8)-(-5又1/2)+(-4又1/4)-(+3又1/8)
=-4+5-4-3-7/8+1/2-1/4-1/8
=-6+1/2-1/4-(7/8+1/8)
=-7+1/4
=-(6又3/4)4又7/8=4+7/85又1/2=5+1/2……原式=-4-7/8+5+1/2-4-1/4-3-1/8=-4+5-4-3-7/8+1/2-1/4-1/8=-6+1/2-1/4-(7/8+1/8)=-7+1/4=-(6又3/4)-7/8+1/2-1/4-1/8=1/2-1/4-(7/8+1/8)1/2是后面提上来的
