Emily had 75 buttons. She gave 15 buttons to Jake. What percent of the buttons did Emily give to Jake? A) 2% B) 10% C) 15% D) 20%

The answer is D, 20%. I got this by starting with the fraction, 15/75 and then you divide the top of the fraction by the bottom (15÷75) and then multiplied it by 100, 20%.
