展开全部
解:4.8除以0.12的商减去8.4所得差再乘以0.01,积是( 79/250 ),【即等于0.316】
∵已知需求出4.8除以0.12的商减去8.4所得差再乘以0.01,积是多少
∴4.8除以0.12的商减去8.4所得差再乘以0.01,积
= (4.8 ÷ 0.12 - 8.4) × 0.01
= (40 - 8.4)× 0.01
= [40 - (8×10+4)/10] × 1/100
= (40 - 84/10)× 1/100
= (400/10 - 84/10)× 1/100
= 316/10 × 1/100
= 158/5 × 1/100
= 158/500
= 79/250
= 0.316
答:4.8除以0.12的商减去8.4所得差再乘以0.01,积是79/250,【即等于0.316】
