小学数学 6.25×1.02÷1.5 如何用简便方法计算

Answer 1

6.25×1.02÷1.5
=（6.25÷5）*（1.02÷0.3）
=1.25*3.4
=1.25*（3+0.4）
=1.25*3+1.25*0.4
=3.75+0.5
=4.25

Answer 2

6.25×1.02÷1.5

=6.25÷1.5 ×1.02
=1.25÷0.3 ×1.02
=1.25 ×1.02÷0.3
=1.25 ×3.4
=4.25

Answer 3

6.25×1.02÷1.5
=（6.25÷5）*（1.02÷0.3）
=1.25*3.4
=1.25*（3+0.4）
=1.25*3+1.25*0.4
=3.75+0.5
=4.25就是这样，不懂再问

Answer 4

6.25×1.02÷1.5 =6.25÷1.5 ×1.02——乘法交换律=（6.25÷5）÷（1.5÷3）×1.02=1.25÷0.3 ×1.02=1.25 ×1.02÷0.3=1.25 ×3.4=4.25

Answer 5

原式=6.25/5*(1.02/0.3)
=1.25*3.4
=1.25*0.8*4.25
=4.25
