Question

用简便方法计算：14.8×6.3＋46.5×4.5＋8.3×3.7＋0.465×550－6.3×6.5

Answer 1

6.3(14.8-6.5)+46.5(4.5+5.5)+8.3*3.7
=6.3*8.3+465+8.3*3.7
=8.3(6.3+3.7)+465
=8.3*10+465
=83+465
=548
你要是觉得行把分给我把

Answer 2

14.8×6.3＋46.5×4.5＋8.3×3.7＋0.465×550－6.3×6.5
=6.3x(14.8-6.5)+46.5x(4.5+5.5)+8.3x3.7
=6.3x8.3+46.5x10+8.3x3.7
=8.3x(6.3+3.7)+465
=83+465
=548
