1.35×38+0.38×25+6.2×16怎么简便？

Answer 1

1.35×38+0.38×25+6.2×16
=1.35×38+38×0.25+6.2×16
=38×（1.35+0.25）+6.2×16
=38×1.6+62×1.6
=（38+62）×1.6
=100×1.6
=160
一个因数扩大（或缩小）若干倍（0除外），另一个因数缩小（或扩大）相同的倍数，积不变。

Answer 2

1.35X38+0.38×25+6.2X16
=13.5X3.8+3.8×2.5+6.2X16
=3.8X(13.5+2.5)+6.2X16
=3.8x16+6.2X16
=16X(3.8+6.2)
=16x10
=160
