用简算写出下列的计算题.0.125×4.25+12.5%+0.125×2.75===十一又六分之五—四又八分之五—五又八分之三===
0.125×4.25+12.5%+0.125×2.75
=0.125×(4.25+1+2.75)
=0.125×8
=1
十一又六分之五—四又八分之五—五又八分之三
=11又5/6-(4又5/8+5又3/8)
=11又5/6-10
=1又5/6
(1)=0.125×4.25+0.125×1+0.125×2.75
=0.125×(4.25+1+2.75)
=0.125×8
=1
(2)=11(5/6)-(4(5/8)+5(3/8))
=11(5/6)-10
=1(5/6)
