The core rule is divide the numerator by the denominator, then multiply by 100 to express the same ratio out of 100.

This guide focuses on symbols and operations, not word problems. If the story is what trips you up, read the introduction there first, then return here for the mechanics.
Main content
What is it?
The formula is a compact sentence for a two-step process. Division answers how large the part is relative to one whole. Multiplication by 100 rephrases that answer as a count out of 100.
Formula
The numerator counts parts you care about. The denominator counts how many equal parts build a whole. Division compares them as a single number.
When you need meaning before symbols, what is a fraction to percentage conversion explains the same idea in plain language.
Step-by-step guide
Write the fraction. Simplify if it helps mental math. Divide numerator by denominator. Multiply by 100. Round only if your context requires it.

Example
For 7/20, divide to get 0.35, then multiply by 100 to report 35%. That pattern appears often when instructors use twenty-point scales.
FAQ
Does multiplying first ever work?
You can scale the fraction first using legitimate equivalent forms, but the textbook route is divide then multiply by 100 unless your teacher shows a different approved path.
Conclusion
You can read the formula as divide then scale. The decimal in the middle is a useful checkpoint when you sanity-check calculator output.
