计算下面各题(4/5+1/4) ÷7/3+7/10 3/4×(1/2÷5/8) 1.21×42-(4.46+0.14)
(4/5+1/4)÷7/3+7/10 =(16/20+5/20)×3/7+7/10 =21/20×3/7+7/10 =9/20+14/20 =23/20 3/4×(1/2÷5/8) =3/4×(1/2×8/5) =3/4×4/5 =3/5 1.21×42-(4.46+0.14) =50.82-4.6 =46.22 (4/5+1/4)÷7/3+7/10 =(16/20+5/20)×3/7+7/10 =21/20×3/7+7/10 =9/20+14/20 =23/20 3/4×(1/2÷5/8) =3/4×(1/2×8/5) =3/4×4/5 =3/5 1.21×42-(4.46+0.14) =50.82-4.6 =46.22 (4/5+1/4)÷7/3+7/10 =(16/20+5/20)×3/7+7/10 =21/20×3/7+7/10 =9/20+14/20 =23/20 3/4×(1/2÷5/8) =3/4×(1/2×8/5) =3/4×4/5 =3/5 1.21×42-(4.46+0.14) =50.82-4.6 =46.22
