Rate-based proportion can be used to calculate the rate of success for any given activity. By understanding how two variables are related, you can calculate the rate of success for a given activity and make informed decisions about how to use your resources most efficiently.

For example, if you’re trying to increase your sales, you can use rate-based proportion to determine the rate of success for different marketing strategies. You can then use this information to make decisions about which strategies to focus on and which to avoid.

Another great way to use rate-based proportion is to calculate the rate of success for different strategies in different situations. For example, if you’re trying to increase sales in a certain market, you can use rate-based proportion to identify the strategies that have the highest rate of success in that market. Example if 3 energy-saving light bulbs cost £7.80. Determine the cost of 7 such light bulbs. Hence, 7 light bulbs cost 7 × £2.60 = £18.20
