Question

0.09×0.02等于几

Answer 1

0.09x0.02＝0.0018。把0.09×0.02列成竖式，运用口诀，二九十八，然后补四位小数，补一位是1.8，两位是0.18，三位是0.018，四位就是0.0018

Answer 2

0.09 x 0.02=0.0018 2乘9等于18，小数点向前移四位就是0.0018
可以先化为分数再计算:
0.09×0.02
=9/100×2/100
=[9/（2×50）]×2/100
=9/50×1/100
=9/5000
也可以同时扩大100倍再计算:
0.09×0.02
=(0.09×100)×(0.02×100)÷（100×100）
=9×2÷10000
=(9×2)÷(5000×2)
=9/5000

Answer 3

0.09×0.02等于几？0.09×0.02等于0.0018。
