What is the percent of increase from 40 to \( 46 ? \)

To find the percent increase from 40 to 46, first, subtract the original value (40) from the new value (46) to get the increase, which is 6. Then, divide that increase by the original value (40), giving you \( \frac{6}{40} = 0.15 \). Multiply that result by 100 to convert it to a percentage: \( 0.15 \times 100 = 15\%\). So, the percent increase is 15%! Understanding percentages is a key skill in various fields! For example, in finance, knowing how much your investments have grown over time can help you make smarter decisions.
