Answer:
15 is 20% of 75. And 15:12.
Explanation:
Emily had 75 buttons. She gave 15 buttons to Jake. What percent of the buttons did Emily give to Jake?
She gave 15 out of her 75 buttons, so we have to figure out what percentage of buttons did she give to Jake. 20 times 5 = 100 and 5 times 15 = 75, so that is how we end up with the answer- 15 is 20% of 75.
