Understanding Fractions and Percentages

Before we dive into the conversion, let's clarify the basics. A fraction represents a part of a whole. The top number is the numerator, and the bottom number is the denominator. A percentage expresses a fraction as parts per hundred. The symbol % denotes a percentage.

Method 1: Direct Conversion

The most straightforward method involves converting the fraction into a decimal and then multiplying by 100%.

Divide the numerator by the denominator: 7 ÷ 20 = 0.35
Multiply the decimal by 100%: 0.35 x 100% = 35%

Therefore, 7/20 is equal to 35%.

Method 2: Finding an Equivalent Fraction

This method involves finding an equivalent fraction with a denominator of 100.

Find a number to multiply the denominator (20) to get 100: 20 x 5 = 100
Multiply the numerator (7) by the same number: 7 x 5 = 35
The equivalent fraction is 35/100: This directly translates to 35%.

Again, we find that 7/20 equals 35%.

Method 3: Using a Calculator

For quick conversions, a calculator is a handy tool. Simply divide the numerator (7) by the denominator (20) and multiply the result by 100. The answer will be 35%.
