Write the simplest ratio of $2.5km$ and $45$ hectometer.

Answer 1

$\begin{array}{c}1km=10\text{hectometer}\\ \text{Thus}2.5km=25\text{hectometer}\end{array}$

$\begin{array}{cc}\frac{2.5Km}{45\text{hecom}}=& \frac{25\text{hectometer}}{45\text{hectometer}}\\ & =\frac{25}{45}\\ & =\frac{5}{9}\end{array}$
