Question

Express each of the following percents as ratios in the simplest form. 

(a) 12% 

(b) 25%

(c) 45% 

(d) 84%

Answer 1

a) Given percent is 12% 

= \(\frac{12}{100}\) = \(\frac{3}{25}\) (fraction form) 

= 3 : 25 (ratio form) 

b) Given percent is 25% 

= \(\frac{25}{100}\) = \(\frac{1}{4}\) (fraction form)

= 1 : 4 (ratio form) 

c) Given percent is 45% 

= \(\frac{45}{100}\) = \(\frac{9}{20}\) (fraction form) 

= 9 : 20 (ratio form) 

d) Given percent is 84% 

= \(\frac{84}{100}\) = \(\frac{21}{25}\) (fraction form) 

= 21 : 25 (ratio form)
