Consider the following proportion:

$75\xf7100=150\xf7200$

The objective is to write the given proportion in the form of a fraction.

If an equation showing the equality of two ratios, then the ratios are called as a proportion.

For example:$x\xf7y=m\xf7n$ or $\frac{x}{y}=\frac{m}{n}$

To write the proportion as a fraction, convert both the ratios in the form of a fraction,$\frac{A}{B}$ , without
reducing the ratios to their lowest terms.

The conversion of$75\xf7100=150\xf7200$ into a fraction is,

$\frac{75}{100}=\frac{150}{200}$

Therefore, the proportion in the form of a ratio is$\frac{75}{100}=\frac{150}{200}$ .
