Simplifying the ratio gives 20/ 9

What is ratio?

Ratio is defined as the comparison of two numbers indicating their size in relation to each other.

A ratio compares two quantities by division.

We have:

1:9:4.5

It can be represented thus;

= 1/ 9/ 4 × 5

Take the inverse of the divisor and multiply

= 1 × 4/ 9 × 5

Multiply through

= 20/ 9

Thus, simplifying the ratio gives 20/ 9
