Understanding Percentages

A percentage is simply a fraction out of 100. When we say "x percent," we mean x parts out of 100. For example, 50% means 50 out of 100, or one-half.

Step 2: Convert the Fraction to a Decimal

Divide the numerator (34) by the denominator (40): 34 ÷ 40 = 0.85

Step 3: Convert the Decimal to a Percentage

Multiply the decimal by 100%: 0.85 x 100% = 85%

• Financial Analysis: Percentage changes are common in financial reports, representing increases or decreases in profits, revenue, or investments.
