THERE ARE FOUR WORD PROBLEMS BELOW. YOUR ASSIGNMENT IS TO DOUBLE CHECK MY WORK. SOLVE THE PROBLEMS. RESPOND ON THIS BLOG TO EACH PROBLEM BY EXPLAINING IF MY ANSWER WAS CORRECT OR INCORRECT.
PROBLEM 1: Sue had 7/12 (seven twelfth) of a piece of ribbon. She cut off 1/4 (one fourth) of the ribbon for a project. How much did she have left?
ANSWER: 1/3 (one third). Is Mr. Adair correct or incorrect? Explain your answer.
PROBLEM 2: Suni needs 2/3 (two thirds) cup white sugar and 1/4 (one fourth) cup brown sugar to make cookies. How much sugar is that all together?
ANSWER: 11/12 (eleven twelfth) cup. Is Mr. Adair correct or incorrect? Explain your answer.
PROBLEM 3: Mrs. Bew bought 5/6 (five sixths) yard of red fabric and 1/2 (one half) yard of green fabric. How much more red fabric than green fabric did Mrs. Bew buy?
ANSWER: 1/3 (one third). Is Mr. Adair correct or incorrect? Explain your answer.
PROBLEM 4: Joey ate 1/4 (one fourth) of a bag of oranges. Billy ate 1/3 (one third) of the same bag of oranges. How much of the bag did they eat together? If there were 48 oranges in the whole bag, how many oranges were left?
ANSWER: They ate 7/12 (seven twelfth) of the bag. 28 oranges are left. Is Mr. Adair correct or incorrect? Explain your answer.
1st one is correct 7/12 -1/4 =1/3
2nd one is correct 2/3 +1/4= 11/12 you answered that
3rd one is correct 5/6 -1/2 =1/3 and your answer was that
4th one is incorrect when I calculated i got 5/12
#1 is correct. 7/12 – 3/12= 4/12 which if you simplify it it = 1/3.
#2 is correct. 2/3 = 8/12 and 1/4 = 3/12 which if you add that it = 11/12.
#3 is correct. 1/2= 3/6 and 5/6 – 3/6 = 2/6 which is one third.
#4 is correct and incorrect. They did eat 7/12. 3/12 + 4/12 is 7/12. But they did not have 28 left. They had 20 left. 1/3 of 48= 16. 1/4 of 48= 12. 16+12 = 28 which if is subtracted from 48 it = 20.
1)correct because you convert 1/4 to have the same denominator as 7/12. Then you subtract them. Then you simplified
2)correct because you multiply 2/3 by four so it is 8/12. Then mutiply 3 to 1/4 so it will be 3/12. Add 8/12 and 3/12 which is 11/12
3)correct because you turn 1/2 into 3/6. Then you subtract 5/6 by 3/6 which is 2/6. Then you simplify to 1/3
4) correct. They did eat 7/12. The ate 7/12 because 1/3 is 4/12 and 1/4 is 3/12. then add them together which is 7/12. You are wrong in the second question because they ate 28, but there is 20 left.
1. Mr.Adair is right because 7/12 – 1/4 = 3/12 that equals 1/3.
2. Mr.Adair is right because 2/3 = 8/12 and 1/4 = 3/12 and 3/12 + 8/12 =11/12
3. Mr.Adair is right because 1/2 = 3/6 and 5/6 -3/6 is 2/6 that equals 1/3
4. Mr.Adair is half right because 1/4 + 1/3 = 7/12 but he does not have 28 oranges left he took 28 oranges
1. Mr. Adair is correct. Because 1/4=3/12. 7/12-3/12=4/12. 4/12=1/3
2. Mr Adair is correct. Because 2/3=8/12. 1/4=3/12. 8/12+3/12=11/12
3. Mr Adair is correct. Because 1/2=3/6. 5/6-3/6=2/6. 2/6=1/3
4. Mr Adair is incorrect. Because 1/4=3/4. 1/3=4/12. 3/12+4/12=7/12. 7/12 is more than half but 28 is more than half of 48. if you take away 7/12 from 48 you get 20.
1) correct
2)
