Understanding Percentages

A percentage is a fraction or ratio expressed as a number out of 100. " So, 3.Which means this can be expressed as a decimal (0. 035) or a fraction (7/200). 5/100. But 5 out of 100, or 3. 5% means 3.The symbol "%" represents "per cent," meaning "out of one hundred.Understanding this basic concept is crucial for solving percentage problems.

Method 1: Converting Percentage to Decimal

This is the most straightforward method. We convert the percentage to a decimal and then multiply it by the given number.

Steps:

1. Convert the percentage to a decimal: Divide the percentage by 100. In this case, 3.5% becomes 3.5 / 100 = 0.035.

2. Multiply the decimal by the number: Multiply the decimal (0.035) by 260,000. This gives us: 0.035 * 260,000 = 9100.

Which means, 3.5% of 260,000 is 9100.

Method 2: Using Fractions

This method involves converting the percentage to a fraction and then performing the multiplication.

Steps:

1. Convert the percentage to a fraction: 3.5% can be written as 3.5/100. To simplify, we can multiply both numerator and denominator by 10 to get rid of the decimal: (3.5 * 10) / (100 * 10) = 35/1000. This fraction can be further simplified by dividing both numerator and denominator by 5: 7/200.

2. Multiply the fraction by the number: Multiply the fraction (7/200) by 260,000: (7/200) * 260,000 = (7 * 260000) / 200 = 1820000 / 200 = 9100.

Because of this, 3.5% of 260,000 is 9100. This method demonstrates the underlying fractional nature of percentages.

Method 3: Proportion Method

This method uses the concept of proportion to solve the problem. We set up a proportion where x represents the unknown value (3.5% of 260,000).

Steps:

1. Set up the proportion: We can express the problem as a proportion: 3.5/100 = x/260,000.

2. Cross-multiply: Cross-multiply the terms to get: 100x = 3.5 * 260,000.

3. Solve for x: Divide both sides by 100 to isolate x: x = (3.5 * 260,000) / 100 = 9100.

Which means, 3.5% of 260,000 is 9100. This method highlights the proportional relationship between percentages and the whole number.
