Understanding Percentages

A percentage is a way of expressing a fraction or ratio as a number out of 100. The symbol "%" represents "percent," which literally means "out of one hundred." Therefore, 50% means 50 out of 100, or 50/100, which simplifies to 1/2.

Calculating 35 out of 50 as a Percentage

To calculate 35 out of 50 as a percentage, follow these simple steps:

Set up a fraction: Express the problem as a fraction: 35/50. This represents 35 parts out of a total of 50 parts.
Convert the fraction to a decimal: Divide the numerator (35) by the denominator (50): 35 ÷ 50 = 0.7
Convert the decimal to a percentage: Multiply the decimal by 100: 0.7 x 100 = 70
Add the percentage symbol: The final answer is 70%.

Therefore, 35 out of 50 is equal to 70%.

Alternative Calculation Method: Using Proportions

Another way to solve this is using proportions:

Set up a proportion: x/100 = 35/50 (where 'x' represents the percentage we're trying to find)
Cross-multiply: 50x = 3500
Solve for x: x = 3500 / 50 = 70
Add the percentage symbol: x = 70%

This method demonstrates the underlying relationship between fractions and percentages.
