Fraction to Percent: (a/b)×100

Convert a fraction to percent: divide a by b, multiply by 100. 1/2 = 50%, 3/4 = 75%. Percent means per hundred—so a/b = (a/b)×100 percent.

📋 Key Takeaways

• Percent = (a/b) × 100. Divide numerator by denominator, then multiply by 100
• Mixed numbers: 1 3/4 = 1 + 3/4 = 1.75 = 175%
• Common fractions: 1/2=50%, 1/4=25%, 3/4=75%, 1/5=20%
• Repeating decimals: 1/3 = 33.33...% — round to desired precision
• Percent means "per hundred" — 75% = 75/100 = 3/4

📖 How It Works

To convert a fraction to a percent, first divide the numerator by the denominator to get a decimal. Then multiply by 100 and append the % symbol. For example: 3/4 = 0.75, and 0.75 × 100 = 75%. For mixed numbers, convert to an improper fraction (or add whole + fraction decimal) first, then apply the same process. Percentages can exceed 100% when the fraction is greater than 1.

📝 Worked Example: 3/4

Step 1: 3 ÷ 4 = 0.75

Step 2: 0.75 × 100 = 75

Result: 3/4 = 75%

Verification: 75% ÷ 100 = 0.75 = 3/4 ✓

⚠️ Common Mistakes to Avoid

Wrong order: a/b means a÷b, not b÷a. 3/4 = 75%, not 133.33%.
Forgetting × 100: 0.75 is the decimal; 75 is the percent. Don't forget to multiply.
Mixed number error: 1 1/2 = 1.5 = 150%, not 11/2 or 50%.
Rounding too early: 1/3 = 33.333...%; round at the end for consistency.
Percent > 100: 5/4 = 125% is valid. Percent can exceed 100.

❓ FAQ

How do I convert a fraction to percent?

Divide numerator by denominator to get decimal, then multiply by 100. E.g. 3/4 = 0.75 = 75%.

What about mixed numbers?

Convert to improper fraction or add: 1 1/2 = 1 + 0.5 = 1.5 = 150%.

Why is 1/3 shown as 33.33%?

1/3 = 0.333... which repeats. We round to 2 decimal places for display.

How do I convert percent back to fraction?

Divide by 100 and simplify. 75% = 75/100 = 3/4.

When would I use this?

Test scores, discounts, recipe scaling, statistics, and any proportion expressed as part of 100.

What if the fraction is greater than 1?

Same formula. 5/4 = 1.25 = 125%. Percent can exceed 100.

What does "percent" mean?

From Latin "per centum" — per hundred. 50% = 50 per 100 = 1/2.

📌 Summary

Converting a fraction to a percent: divide numerator by denominator, multiply by 100, add the % symbol. Mixed numbers are converted by first expressing as a decimal (whole + fraction), then multiplying by 100. Percent means "per hundred" and is widely used in grades, finance, discounts, and statistics.

✅ Verification Tip

Divide the percent by 100 — you should get the original decimal/fraction. For 75%: 75 ÷ 100 = 0.75 = 3/4 ✓.
