Answer:
20%
Explanation:
so he made a total of 70 bowling attempts, and 14 out of those 70 he actually knocked all of the pins down, so what its asking, is what is 14 precent of 70 because the wording is "out of" which means its a part of the entire 70. so you now know what its asking, how do you solve it? well, you would divide 14 by 70 to get the answer in decimal form: 14 / 70 = 0.2000 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.2000 * 100 = 20.00%
