问题2：将以下百分比转换为分数和比率：
Explanation: To convert percentage into fraction and ratios, we need to divide the number by 100 and reduce the fraction to lowest possible term.
Note: Don’t forget to remove the percentage sign.
a)25％
解决方案：
25/100 (Divide numerator and denominator by 5)
= 5/20 (Divide numerator and denominator by 5)
= 1/4
=1:4
b)2.5％
解决方案：
2.5/100
= 25/1000 (Divide numerator and denominator it by 25)
= 1/40
= 1:40
c)0.3％
解决方案：
0.3/100
= 3/1000
= 3:1000
d)125％
解决方案：
125/100 (Divide numerator and denominator by 25)
= 5/4
= 5:4
问题3：将以下内容表示为小数：
Explanation: To convert percent into fraction divide it by 100 and then convert fraction into decimal values.
a)27％
解决方案：
27/100
= 0.27
b)6.3％
解决方案：
6.3/100
= 0.063
c)32％
解决方案：
32/100
= 0.32
d)0.25％
解决方案：
0.25/100
= 0.0025
e)7.5％
解决方案：
7.5/100
= 0.075
f)(1/8)％
解决方案：
(1/8)/100 (100 will get multiplied by 8)
= 1/800
= 0.00125
