We need to find the increase of N240 by the ratio 3:5.
Multiply the original amount by the ratio: 240 × 5 3 .
Calculate the result: 5 240 × 3 = 144 .
The increase is N\boxed{144}.
Explanation
Understanding the Problem We are asked to find the increase of N240 by the ratio 3:5. This means we need to calculate what 3/5 of N240 is.
Setting up the Calculation To find the increase, we multiply the original amount (N240) by the given ratio (3/5). So, we need to calculate: I n cre a se = 240 × 5 3
Calculating the Increase Now, let's perform the calculation: I n cre a se = 240 × 5 3 = 5 240 × 3 = 5 720 = 144
Final Answer Therefore, the increase of N240 by the ratio 3:5 is N144.
Examples
Understanding ratios is very useful in everyday life. For example, if you are baking a cake and the recipe needs to be scaled up or down, you can use ratios to adjust the amount of each ingredient. Similarly, in business, ratios are used to calculate profit margins, growth rates, and other important financial metrics. Ratios help us understand proportions and make informed decisions.
