9/100 ÷ 3/10 ÷ 1/2
= 9/100 x 10/3 x 2
= 90 / 300 x 2
= 3/10 x 2
= 6/10
= 3/5
如果除數為分數，分子及分母會被癲倒，而被除數則維持一變。

你有冇計數機??
你按0.09÷0.3÷0.5
之後按=
之後按ab/c
就ok

1. 0.09 = 9/100 , 0.3 = 3/10 , 0.5 = 1/2 (9/100即係100分之9)
2. = (9/100) / (3/10) ÷ 1/2
3. = (3/10) / (1/2)
4. = 3/10 * 2/1 ( * 即係乖)
5. = 3/5
唔知我表達得好唔好呢......希望幫到你

0.09÷0.3÷0.5
=(0.09÷0.3÷0.5)x100
=9x30x50
=0.006x100
=0.6 / 五分之三
=(0.09÷0.3÷0.5)x100
