简便计算：6.25×0.16＋264×0.0625＋52×0.0625＋62.5×0.2
简便计算：6.25×0.16＋264×0.0625＋52×0.0625＋62.5×0.2

简便计算：6.25×0.16＋264×0.0625＋52×0.0625＋62.5×0.2
6.25×0.16＋264×0.0625＋52×0.0625＋62.5×0.2
=6.25x0.16+6.25x2.64+6.25x2
=6.25x(0.16+2.64+2)
=6.25x4.8
=2.5x2.5x8x0.6
=(2.5x8)x(2.5x0.6)
=20x1.5
=30

6.25×0.16＋264×0.0625＋52×0.0625＋62.5×0.2
=6.25×0.16＋2.64×6.25＋0.52×6.25＋6.25×2
=6.25x(0.16+2.64+0.52+2)
=6.25x5.32
=33.25

6.25×0.16＋264×0.0625＋62.5×0.2
＝0.0625×16＋0.0625×264＋0.0625×200
＝0.0625×﹙16＋264＋200﹚
＝0.0625×480
＝0.625×48
＝5/8×48
＝30.

原式=6.25×0.16＋2.64×6.25＋0.52×6.25＋6.25×2
=6.25x(0.16+2.64+0.52+2)
=6.25x5.32
=33.25
