Extra Help for Final Exams

You found it. I mentioned in class that you could find extra help here for the Final Exam. Here it is:

6th Grade Can you solve these?
1. ¾ + 1/8 =
[A] 1 [B] 5/8 [C] 7/8 [D] 12/16
**These fractions must have the same denominator. The LCD is 8, so you must multiply the top and bottom of 3/4 by 2. The resulting fraction is 6/8. 6/8 plus 1/8 equals 7/8. The correct answer is "C."
2. 2/5 + 1/6 =
[A] 3/11 [B] 2/30 [C] 5/30 [D] 17/30
**Again change into the LCD, which is 30. Multiply 2/5 times 6 on the top and bottom and you will get 12/30. Multiply 1/6 by 5 on the top and bottom and you will get 5/30. 12/30 + 5/30 = 17/30. So the correct answer is "D."

7th Grade Can you solve these?
Write each percent as a fraction in simplest form.
20. 68 % A) 68/100 B) 34/50 C) 17/25 D) 6/8
**Re-write 68 percent as 68/100. Remember, you can REDUCE that fraction by dividing the top and bottom by 4. The result is 17/25. The correct answer is "C."
21. 95 % A) 9/5 B) 19/20 C) 49/50 D) 95/100
**Re-write 95 percent as 95/100, then reduce. The result is 19/20. The correct answer is "B."
