怎样简便怎样计算 ① 1.8×[﹙4.6＋2.4﹚÷0.35] ②0.36×98＋3.6×0.2③﹙11分之3×100分之87﹢100分之73×11分之3﹚÷3％
① 1.8×[﹙4.6＋2.4﹚÷0.35]
= 1.8 x 7 /0.35
= 1.8 x 700/35
= 1.8 x 20
= 36
②0.36×98＋3.6×0.2
= 3.6 x 9.8 +3.6x0.2
=3.6 x (9.8+0.2)
=3.6 x 10
=36
③﹙11分之3×100分之87﹢100分之73×11分之3﹚÷3％
= 3/11 x (87%+73%) / 3%
= 3/11 x 160% /3%
= 3/11 x 160/3
= 160 /11
