Let's get our percentage formula: 100 × numerator / denominator = percentage. We want to find out the numerator. Let's move all the other parts of the equation to the other side. Divide both sides by 100 (to get rid of 100 on the left) and then multiply both sides by the denominator. This is what we get: numerator = percentage × denominator / 100.
