✔ 最佳答案
1. 100L*9%=9L
2.20M*65%
=13M
3.40KG*52%
=20.8KG
4.$5000*0.5%
=$25
2010-07-27 17:15:08 補充：
100%=100/100 所以其他同樣道理 所以將%化為分數
1.100L*9%
=100L*9/100
=9L
2. 20M*65%
=20M*65/100
=13M
3. 40KG*52%
=40KG*52/100
=20.8KG
4. $5000*0.5%
=$5000*0.5/100
=$25

1. 100x0.09=9L (9%->0.09)
2. 20x0.65=13m (65%->0.65)
3. 40x0.52=20.8kg (52%->0.52)
4. 5000x0.005=$25 (0.5%->0.005)
2. 20x0.65=13m (65%->0.65)
3. 40x0.52=20.8kg (52%->0.52)
4. 5000x0.005=$25 (0.5%->0.005)
