36.8×0.4-12.5简便计算
36.8×0.4-12.5简便计算

36.8×0.4-12.5简便计算
36.8×0.4-12.5
=37×0.4-(0.2×0.4+12.5)
=14.8-12.58
=2.22

36.8×0.4-12.5
=36.8×0.4-31.25×0.4
=（36.8-31.25）×0.4
=5.55×0.4
=2.22

36.8×0.4-12.5
=36.8×0.4-31.25×0.4
=（36.8-31.25）×0.4
=5.55×0.4
=2.22这样做的道理因为31.25*0.4=12.5

这道题没用简便计算直接先乘后减
36.8×0.4-12.5
= 14.72-12.5
=2.22
