How to find out what percentage one number is of another number?

For example, what percent is 347 if the main number is 489? To make sure 100% I am phrasing this correctly, if I were to use the same set up as above I would be asking what percentage 50 is if the main number is 100 and the answer would be 50%. Could someone help with the formula?

You divide the number in question by 100 and then multiply it by the number you wish to find the percentage of eg 25% of 34 first divide the34 by 100 to get 1% then simply multiply by 25 so your answer is 8.5

Profile image! Using your example, take the first number(347) and divide by second 489, then times by 100. 347/489 = 0.709 *100 = 70.9%.
