38/78 as a percentage is 48.72%. This number tells you how much of a whole the fraction represents when you look at it in terms of hundredths. The fraction itself can be simplified to 19/39, but the percentage stays the same after rounding to two decimal places.
Seeing the fraction as a percent makes it easier to compare with other values that are already expressed in percentages. For example, if a test score is 48.72% and another is 55%, you can quickly tell the second score is higher without having to work with the original fractions.
In everyday life, percentages like 48.72% are useful for things like discounts, statistics, and measurements. Knowing that 38 out of 78 is about half the whole (just under 50%) gives a clear picture of proportion without needing detailed calculations.
