Question

3.25×9.4有简便方法吗

Answer 1

这是一道乘法运算题,考虑用乘法分配律简化运算,具体步骤如下: 3.25×9.4 =3.25×(10-0.6) =32.5-3.25×0.6 =32.5-1.95 =30.55

Answer 2

3.25=3+0.25
因为，9.4=10-0.6，3.25=3+0.23
所以
3.25×9.4
=（3+0.25）×9.4
=3×9.4+0.25×9.4
=3×（10-0.6）+0.25×（10-0.6）
=30-1.8+2.5-0.15
=32.5-1.95
=30.55

Answer 3

这是一道乘法运算题,考虑用乘法分配律简化运算,具体步骤如下: 3.25×9.4 =3.25×(10-0.6) =32.5-3.25×0.6 =32.5-1.95 =30.55

Answer 4

这是一道乘法运算题,考虑用乘法分配律简化运算,具体步骤如下: 3.25×9.4 =3.25×(10-0.6) =32.5-3.25×0.6 =32.5-1.95 =30.55

Answer 5

3.25×9.4
=3.25×（9+0.4）
=3.25×9+3.25×0.4
=29.25+13
=42.25
