Additional Information•••

Lets take an example..

100, 200, 500, 1000

To verify whether two sets of ratios are in proportional–

Step- 1 → Find the product of the extremes. (First and last numbers).

100 × 1000 = 100000

Step-2 → Find the product of means (the two middle numbers).

500 × 200 = 100000

Product of extremes = product of means

Therefore, the following ratios are in proportion.
