• # question_answer If $3\frac{1}{4}%$ of a number is 0.13 what will be 400% of it? A) $\frac{4}{13}$                         B) $13.0$C) $16.0$ D) $12.4$

(c) Let the number be$x$. $3\frac{1}{4}%$ of $x=0.13\Rightarrow \frac{13}{4}%$ of$x=0.13$ $\Rightarrow$$\frac{13}{400}x=0.13$ $x=\frac{0.13\times 400}{13}=\frac{400}{100}=4$ $\therefore$$400%$ of $4=\frac{400}{100}\times 4=16.0$
