Example: Express each of the following percentages into a fraction in its lowest terms:

i. 17% = \( \frac{17}{100} \)   

ii. 45% =   \( \frac{45}{100} \\ = \frac{9}{20} \) 

iii. 10%  =    \( \frac{10}{100}\\ = \frac{1}{10} \) 

iv. 115% =    \( \frac{115}{100}\\ = \frac{23}{20} \) 

v. 1%  =    \( \frac{1}{100} \) 

vi. 3.5%  =    \( \frac{35}{10} \scriptsize \% \\ = \normalsize \frac{35}{10} \: \times \: \frac{1}{100} \\ = \frac{7}{200} \)
