Answer 2

Preston is making cookies. He has fraction 4 over 5 cup of flour in a bag. He then used two fraction 1 over 10 cup scoops of flour for his recipe. Which of these best explains the amount of flour left in the bag?

fraction 6 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 3 over 10
fraction 5 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 3 over 10
fraction 6 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 2 over 10
fraction 5 over 10, because fraction 3 over 4 minus 2 times fraction 1 over 8 equals fraction 3 over 4 minus fraction 3 over 8
