Question

8×(0.5+3.6)-4.6怎么巧算？

要过程，要巧算

Answer 1

8×(0.5+3.6)-4.6
=8×4.1-4.6
=8×(4+0.1)-(4+0.6)
=8×4+8×0.1-4-0.6
=32+0.8-4-0.6
=(32-4)+(0.8-0.6)
=28+0.2
=28.2

Answer 2

您好就是直接计算即可，相当于8*4.1-4.6，就是32.8-4.6，结果就是28.2

Answer 3

8×(0.5+3.6)-4.6
=8×(0.5+3.5+0.1)-4.6
= 8×(4+0.1)-4.6
= 8×4+8×0.1-4.6

=32+0.8-4.6
=32.8-4.6
=28.2

Answer 4

8X(0.5+3.6)-4.6
=3.6X8+8X0.5-4.6
=4X8-0.4X8-(4.6-4)
=32-3.2-0.6
=32-4+0.2
=28.2
希望采纳，谢谢

Answer 5

8X(0.5+3.6)-4.6
=3.6X8+8X0.5-4.6
=4X8-0.4X8-(4.6-4)
=32-3.2-0.6
=32-4+0.2
=28.2
