Consider the following proportion:

\(\displaystyle{50}\div{25}\div{10}\div{5}\)

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: \(\displaystyle{x}\div{y}={m}\div{n}\) or \(\displaystyle{\frac{{{x}}}{{{y}}}}={\frac{{{m}}}{{{n}}}}\)

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

The conversion of \(\displaystyle{50}\div{25}={10}\div{5}\) into a fraction is,

\(\displaystyle{\frac{{{50}}}{{{25}}}}={\frac{{{10}}}{{{5}}}}\)

Therefore, the proportion in the form of a ratio is \(\displaystyle{\frac{{{50}}}{{{25}}}}={\frac{{{10}}}{{{5}}}}\).
