Question

Convert the following ratios into percentage.

(i) 15 : 25 (ii) 47 : 50 ​ (iii) $\frac{7}{10}$ (iv) $\frac{546}{600}$ (v) $\frac{7}{16}$

Answer 1

(i)
15 : 25 = $\frac{15}{25}=\frac{15}{25}\times 100\%$ = 15 × 4% = 60%

(ii)
47 : 50 = $\frac{47}{50}=\frac{47}{50}\times 100\%$ = 47 × 2% = 94%

(iii)
$\frac{7}{10}=\frac{7}{10}\times 100\%$ = 7 × 10%= 70%

(iv)
$\frac{546}{600}=\frac{546}{600}\times 100\%=\frac{546}{6}\%$ = 91%

(v)
$\frac{7}{16}=\frac{7}{16}\times 100\%=\frac{700}{16}\%$ = 43.75%
