2800÷56简便运算过程如下:
2800÷56
=(400x7)÷(7x8)
=400x7÷7÷8
=(400÷8)x(7÷7)
=50x1
=50
所以2800÷56简便运算的最后结果是50。
扩展资料:
两数相乘直接适用的只有乘法交换律,并不能使计算简便,所以需要通过拆项变成同级运算或两级运算。
1、有一个数接近整百(整十、整千类似)
将接近整百的数拆成“整百+几”或“整百-几”。
例87×99
=87×(100-1)
=87×100-87×1
=8700-87
=8613
2、有一个数是25或125
遇25拆4,遇125拆8
例25×28
=25×(4×7)
=25×4×7
=100×7
=700
