^a/_b = ?% Turn it to a Percent: Convert and Write Integer and Decimal Numbers, Fractions, Ratios and Proportions As a Percentage

It's very simple to write a fraction (a proportion or a ratio) or a decimal number as a percentage.

To convert a fraction:

• - start by dividing the numerator by the denominator
• - then multiply the result by 100%
• By multiplying the result by 100% the value we've got at the previous step is not modified, since 100% = 100/100 = 1
• By multiplying by 100% only the form is being changed - it's written as a percentage.

It's even simpler to write an integer or decimal number as a percentage:

• - simply multiply the number by 100%

Examples

• ¹/₄ = 0.25 = 0.25 × 100% = (0.25 × 100)% = 25%;
• ⁷/₈ = 0.875 = 0.875 × 100% = (0.875 × 100)% = 87.5%
• ^1.3/_9.4 ≈ 0.138297 = 0.138297 × 100% = (0.138297 × 100)% = 13.8297%
• 4.3 = 4.3 × 100% = (4.3 × 100)% = 430%;
