數學題.......

1.1 首先將佢地變為分數, 然後通分母(麻煩左少少=.=")
87又5分之4percent=87.8%=87.8/100=(87.8*9)/(100*9)=790.2/900
9分之8=8/9=(8*100)/(9*100)=800/900
0.892=892/1000=(892*0.9)/(1000*0.9)=802.8/900

1.2 首先將佢地變為百分數(冇咁麻煩^.^)
87又5分之4percent=87.8%(唔使變=.=)
9分之8=8/9*100%=800/9%=88又9分之8percent
0.892=892/1000=89.2%

總結:你最好用第2個方法......

2. 然後排列呢3個數:
因為89.2%>88又8/9%>87.8%
所以0.892>9分之8>87又5分之4percent

希望幫到你~!

87又5分之4=87.8乘100%=8780%
9分之8=0.8（循環小數）乘100%=88.8（循環小數）%
0.892=0.892乘100%=89.2%
由此可見：87又5分之4>0.892>9分之8
由此可見：87又5分之4大過0.892大過9分之8

0.892>9分之8>87又5分之4percent

我以小數作比較

計法:

87又5分之4percent
=87.8%
=87.8/100
=0.878

9分之8
=8/9
=0.88888888888888888888

所以:0.892>9分之8>87又5分之4percent

0.892>9分之8>87又5分之4percent

u can convert them to a fraction over 100 or you can change the fractions and percentages to a decimal number

e.g. 87又5分之4percent = 0.878 ,9分之8 = 0.888

then 0.892 > 9分之8 > 87又5分之4percent

87又5分之4percent=0.878
9分之8=0.8888888......
0.892
So 0.892>9分之8>87又5分之4percent

Why 9分之8=0.8888888...=0.888...
Because you can try dividing 8 by 9.
Hope you can learn it!

87又5分之4percent = (439/4)/100 = 1.0975
9分之8 =8/9 =0.8(循環小數)
0.892

so 87又5分之4percent , 0.892 , 9分之8

87.8%,8/9,0.892
=0.878,0.88,0.892
0.892>9分之8>87又5分之4percent
