0.79x0.46+7.9x0.24+11.4x0.079简便运算怎么做李辩

0.79x0.46+7.9x0.24+11.4x0.079
＝0.79x0.46+0.79x2.4+1.14x0.79
＝0.79 x(0.46+2.4+1.14)
=0.79x4
=(0.8-0.01)X4
=0.8X4-0.01X4
=3.2-0.04
=3.16

0.79乘0.64加7.9乘0.24加11.4乘0.079用简便方法计算

0.79 × 0.64 + 7.9×0.24 + 11.4 × 0.079
= 0.79 × 0.64 + 0.79 × 2.4 + 1.14 × 0.79
= 0.79 × （0.64 + 2.4 + 1.14）
= 0.79 × 4.18
= 3.3022
