Question

0.264✖️519+264✖️0.481两种简便计算方法？

Answer 1

0.264✖️519+264✖️0.481
=0.264x1000x0.519+264x0.481
=264x0.519+264x0.481
=264x（0.519+0.481）
=264x1
=264
0.264✖️519+264✖️0.481
=0.264x519+0.264x1000x0.481
=0.264x（519+481）
=0.264x1000
=264

Answer 2

0.264X519+264x0.481
=0.264x519+(0.264X1000)x0.481
=0.264╳519+0.264x(1000X0.481)
=0.264X(519+481)
=0.264X1000
=264
0.264x519+264x0.481
=(264x0.001x519)+264x0.481
=264x0.519+264x0.481
=264x(0.519+0.481)
=264X1
=264

Answer 3

0.264X519+264x0.481
=0.264x519+(0.264X1000)x0.481
=0.264╳519+0.264x(1000X0.481)
=0.264X(519+481)
=0.264X1000
=264
0.264x519+264x0.481
=(264x0.001x519)+264x0.481
=264x0.519+264x0.481
=264x(0.519+0.481)
=264X1
=264

Answer 4

没有一没有1000，也没有0.519，这怎么算呀？
