Understanding Percentages

A percentage is a way of expressing a number as a fraction of 100. The symbol % means "out of 100" or "per hundred." For example, 50% means 50 out of 100, or 50/100, which simplifies to 1/2.

Calculating 43 out of 50 as a Percentage

There are two main ways to calculate 43 out of 50 as a percentage:

Method 1: Using a Fraction

Express as a fraction: Write 43 out of 50 as a fraction: 43/50.
Convert to a decimal: Divide the numerator (43) by the denominator (50): 43 ÷ 50 = 0.86
Convert to a percentage: Multiply the decimal by 100: 0.86 x 100 = 86%

Therefore, 43 out of 50 is equal to 86%.

Method 2: Using Proportions

This method is particularly useful for understanding the underlying concept.

Set up a proportion: We want to find x, where x/100 represents the percentage. Our proportion is: 43/50 = x/100.
Cross-multiply: Multiply 43 by 100 and 50 by x: 4300 = 50x.
Solve for x: Divide both sides by 50: x = 4300 ÷ 50 = 86.

Therefore, x = 86, meaning 43 out of 50 is 86%.
