A mathematical comparison between two different numbers is known as ‘proportions’. In general, it is referred to as the part, number, or share considered in comparative relation to a whole. When two ratios are equal or equivalent, they are meant to be in proportion. They are generally denoted using the symbol, ‘=’ or ‘::’. For instance, the time taken by a car to cover 60 km per hour is equal to the time taken by it to cover the distance of 300 km for 5 hours. So, 60 km / hr = 300 km / 5hr.
