1. Express each of the following percents as fractions in the simplest forms:
(i) 45%
(ii) 0.25%
(iii) 150%
(iv) 6 1/4 %
Solution:
(i) Given 45%

On simplifying the above fraction we get
= (9/20)
(ii) Given 0.25%
= (0.25/100)
= (25/10000)
On simplifying the above fraction we get
= (1/400)
(iii) Given 150%
= (150/100)
On simplifying the above fraction we get
= (3/2)
(iv) Given 6 1/4 %
We can write 6 1/4 as 6.25
= (6.25/100)
