You divide the number you want to find the percentage of by the total number present (and then times by 100). For example - if you invite 15 people to a meeting and 12 turn up, to find the percentage you divide 12 by 15 and then times by a hundred. 12 ÷ 15 = 0.8 = 80%
To find the percentage, divide the part (12) by the whole (15) and then multiply by 100. (12 / 15) * 100 = 80% Therefore, 12 is 80% of 15.
