5.60成69.32家138.64成0.05家693.2成0.43简算
5.60成69.32家138.64成0.05家693.2成0.43简算

5.60成69.32家138.64成0.05家693.2成0.43简算
5.60*69.32+138.64*0.05+693.2*0.43
=5.60*69.32+69.32*2*0.05+69.32*10*0.43
=5.60*69.32+69.32*0.1+69.32*4.3
=69.32*（5.60+0.1+4.3）
=69.32*10
=693.2

把138.64化成69.32乘以2把693.2化成69.32乘以2，再整理一下就成了，答案是六九三点二

5.60 x 69.32+138.64 x 0.05+693.2 x 0.43
=5.60 x 69.32+69.32 x 2 x 0.05+69.32 x 10 x 0.43
=5.60 x 69.32+69.32 x (2 x 0.05)+69.32 x (10 x 0.43)
=5.60 x 69.32+69.32 x 0.1+69.32 x 4.3
=69.32 x (5.60+0.1+4.3)
=69.32 x 10
=693.2

5.6*69.32+138.64*0.05+693.2*0.43
=5.6*69.32+69.32*2*0.05+69.32*10*0.43
=5.6*69.32+69.32*0.1+69.32*4.3
=69.32*(5.6+0.1+4.3)
=69.32*10
=693.2
