Question

Express each of the following per cents as fractions in the simplest forms:
(i) 45%
(ii) 0.25%
(iii) 150%
(iv) $6\frac{1}{4}\%$

Answer 1

(i) 45% = 45/100 = 9/20
(ii) 0.25% = 0.25/100 = 25/10000 = 5/2000 = 1/400
(iii) 150% = 150/100 = 15/10 = 3/2
(iv) $6\frac{1}{4}\%=\frac{25}{4}÷100=\frac{25}{100\times 4}=\frac{1}{16}$
