问题描述：
(5/12-5/16)×4/5+2/3-3/4 能简算就简算
1.(5/12-5/16)×4/5+2/3-3/4
2.【1-（1/3-1/6）】×2/5
答
1.(5/12-5/16)×4/5+2/3-3/4
=5/12*4/5-5/16*4/5+2/3-3/4
=1/3-1/4+2/3-3/4
=1/3+2/3-(1/4+3/4)
=1-1
=0
2.【1-（1/3-1/6）】×2/5
=(1-1/6)*2/5
=5/6*2/5
=1/3
√希望你能看懂，你能明白， 望采纳，赞同
答
原式=3分之1一4分之1十3分之2一4分之3
=1一1
=0.
2.原式=[1一6分之1]x5分之2
=6分之5x5分之2
=3分之1.
