✔ 最佳答案
6/5d = 15
6/5d * 5d = 15*5d
6 = 75d
d = 6/75
d = 0.08

Hope that can hope you la... ^^

以上果個係 6 ÷ 5d = 15 嘅答案;可能你果個係 5 分之 6 d =15,所以我例埋後者嘅答案:5/6 d = 155/6 d ÷ 5/6 = 15 ÷ 5/6d = 15 * 6/5d = 18希望幫到你啦…

中間出左D錯,唔好意思,正確答案如下:6 ÷ 5d = 15 6 ÷ 5d * 5d = 15*5d6 = 75dd = 6 ÷ 75d = 0.085 分之 6 d =156/5 d ÷ 6/5 = 15 ÷ 6/5d = 15 * 5/6d = 12.5希望幫到你啦…

5/6 d=15

5d=90---->(15x6)

d=18------>(90除5)

係6/(5d) 定係(6/5)d?
6/(5d):
6/(5d)=15
6/15=5d
(2/5)/5=d
d=0.08

(6/5)d:
(6/5)d=15
d=15*(5/6)
d=12.5

6/5d=15
6=15 * 5d
6=75d
d=6/75
d=0.08

6/5d=15
d=15X5/6
d=12.5
