做一個砵仔糕需用粘米粉:
(3 3/4 x 2/25) / 9
=(15/4 x 2/25) / 9
=(3/10) /9
=1/30 (kg)
(3 3/4 x 2/25) / 9
=(15/4 x 2/25) / 9
=(3/10) /9
=1/30 (kg)

平均做一個砵仔糕需用粘米粉:
(3 3/4x2/25)/9
=3/10/9
=0.3/9
=3/90
=1/30(kg)
(3 3/4x2/25)/9
=3/10/9
=0.3/9
=3/90
=1/30(kg)

平均做一個砵仔糕需用粘米粉:
3又4分之3x25分之2除以9
=3/10除以9
=1/30(kg)
3又4分之3x25分之2除以9
=3/10除以9
=1/30(kg)

3又4分之3除(25分之2除9)
＝3又4分之3除112.5
=30分之1(kg)
＝3又4分之3除112.5
=30分之1(kg)

(3又4分之3 乘以 25分之2) 除以9
=10分之3除以9
=30分之1
=10分之3除以9
=30分之1
2008-06-09 4:51 am
3又4分之3 x 25分之2 / 9
= 30分之1
= 30分之1
