Question

Express each of the following per cents as ratios in the simplest form:

(i) 2.5%

(ii) 0.4%

(iii) 13 (3/4) %

Answer 1

(i) Given 2.5%

= (2.5/100)

= (25/1000)

= (1/40)

(ii) Given 0.4%

= (0.4/100)

= (4/1000)

= (1/250)

(iii) Given 13 (3/4) %

13 (3/4) = 13.75

= 13.75/100

= 1375/10000

= 11/80
