Question

3.83×4.56+38.3×0.544的简便计算？

Answer 1

3.83×4.56+38.3×0.544的简便计算的列式中可能后面的那个数字是0.54，而不是0.544，这样才有简便计算方法。那么简便计算列式应该这样的：
3.83×4.56+38.3×0.54
=3.83x（4.56+0.54）
=3.83X5
=19.15

Answer 2

3.83x4.56+38.3x0.544
观察得：3.83x4.56+3.83x10x0.544
=3.83x4.56+3.83x5.44
提取公因式：3.83x(4.56+5.44)
=3.83x10
=38.3

Answer 3

3.83×4.56+38.3×0.544
=3.83×4.56+3.83×（10×0.544）
=3.83×4.56+3.83×5.44
=3.83×（4.56+5.44）
=3.83×10
=38.3

Answer 4

3.83×4.56+38.3×0.544
=3.83×4.56+3.83×5.44…(38.3÷10=3.83，0.544×10=5.44)
=3.83×(4.56+5.44)
=3.83×10
=38.3

Answer 5

3.83×4.56+38.3×0.544=3.83×4.56+3.83×5.44=3.83*(4.56+5.44)=3.83*10=38.3
