6/20 + 5/20 + 4/20 =
Correct Answer
D. 3/4
Explanation
The given expression represents the sum of three fractions with a common denominator of 20. Adding the numerators of the fractions gives 6 + 5 + 4 = 15. Therefore, the sum is 15/20, which can be simplified to 3/4.
34.
7/12 + 3/12 =
Correct Answer
B. 5/6
Explanation
The given question asks for the sum of 7/12 and 3/12. To find the sum of fractions with the same denominator, we add their numerators and keep the denominator the same. Therefore, 7/12 + 3/12 = (7+3)/12 = 10/12. Simplifying this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2, we get 5/6. Therefore, the correct answer is 5/6.

Thus, 7/9 + 8/9 = (7+8)/9 = 15/9. However, this fraction can be simplified to its simplest form, which is 1 2/3. Therefore, the correct answer is 1 2/3.
36.
7/10 - 3/10 =
Correct Answer(s)
A. 1/5
E. None of These
Explanation
The correct answer is 1/5 because when subtracting fractions, we need to have a common denominator. In this case, the common denominator is 10. So, 7/10 - 3/10 is equal to (7-3)/10, which simplifies to 4/10. To further simplify, we can divide both the numerator and denominator by their greatest common factor, which is 2. Thus, 4/10 simplifies to 2/5. Therefore, the correct answer is 1/5.
37.
5/7 + 1/7 =
Correct Answer
B. 6/7
Explanation
When adding fractions, we need to have a common denominator. In this case, the denominators are already the same, which is 7. So we can simply add the numerators together, which gives us 5+1=6. Therefore, the sum of 5/7 and 1/7 is 6/7.
38.
6/8 - 3/8 =
Correct Answer
C. 3/8
Explanation
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 8. So, 6/8 - 3/8 is equal to (6-3)/8, which simplifies to 3/8. Therefore, the correct answer is 3/8.
39.
4/8 + 1/8 =
Correct Answer
B. 5/8
Explanation
