Question

What percent is $7m25cmof58m$.

Answer 1

Step 1: Converting values in same unit.

Converting $m$ into $cm$ using relation $1m=100cm$, we get:

$7m25cm$ in $cm$:

$$\begin{gathered} \Rightarrow 7m=7\times 100cm=700cm \\ \therefore 7m25cm=700cm+25cm=725cm \end{gathered}$$

$58m$ in $cm$:

$\Rightarrow 58m=58\times 100cm=5800cm$

Step 2: Finding the percentage.

$$\begin{gathered} \Rightarrow \left(\frac{725}{5800}\times 100\right)\%=\left(\frac{725}{58\cancel{00}}\times 1\cancel{00}\right)\% \\ \Rightarrow \left(\frac{725}{58}\right)\%=12.5\% \end{gathered}$$

Hence, $7m25cm$ will be $12.5\%$of $58m$.
