解:0.38×0.23等于( 437/5000 ),【即等于0.0874】
∵已知需求出0.38×0.23等于多少
∴0.38 × 0.23
= 38/100 × 23/100
= 19/50 × 23/100
= (19×23)/(50×100)
= 437/5000
= 0.0874
答:0.38×0.23等于437/5000,【即等于0.0874】
0.38×0.23
=0.38×(0.2+0.03)
=0.38×0.2+0.38×0.03
=0.076+0.0114
=0.0874
0.38x0.23
=0.23x0.4-0.23x0.02
=0.092-0.0046
=0.09156
