Find the missing figures: (i) ?\% of 25 = 2.125 (ii) 9\% of ? = 63 (iii) 0.25\% of ? = 0.04
Answer
Explanation
(i) Let $x \%$ of $25=2.125$. Then, $\frac{x}{100} \times 25=2.125 \Leftrightarrow x=(2.125 \times 4)=8.5$. (ii) Let $9 \%$ of $x=6.3$. Then, $\frac{9}{100} x=6.3 \Leftrightarrow x=\left(\frac{6.3 \times 100}{9}\right)=70$. (iii) Let $0.25 \%$ of $x=0.04$. Then, $\frac{0.25}{100} x=0.04 \Leftrightarrow x=\left(\frac{0.04 \times 100}{0.25}\right)=16$.
