In the realm of mathematics, understanding percentages is crucial for various calculations. One such conundrum that often arises is determining "what percent of 80 is 30." To unravel this puzzle, let's delve into the essential concepts and provide you with a step-by-step guide.

Understanding Percentages

A percentage represents a fraction of a total amount expressed as a value out of 100. For instance, 50% signifies half of the whole. To convert a percentage to a decimal, simply divide it by 100. Conversely, to convert a decimal to a percentage, multiply it by 100.

Percentage	Decimal
50%	0.5
25%	0.25
75%	0.75

Calculating Percentages

To determine what percent of 80 is 30, follow these steps:

Divide the part (30) by the whole (80).

30 ÷ 80 = 0.375

Multiply the result by 100 to convert it to a percentage.

0.375 × 100 = 37.5%

Therefore, 30 is 37.5% of 80.

Part	Whole	Percentage
30	80	37.5%
20	50	40%
45	90	50%
