What is 5/14 + 6/7 as an improper fraction?

• A. 15/14
• B. 18/14
• C. 17/14
• D. 16/14

Answer: (C)

When adding fractions with different bottom numbers, make the denominators the same. Here, use 14 as the common denominator because 7 times 2 equals 14. Convert 6/7 to an equivalent with denominator 14: 6/7 = 12/14. Now add the numerators: 5/14 + 12/14 = 17/14. The result is an improper fraction since the numerator (17) is larger than the denominator (14). If you prefer a mixed number, it would be 1 and 3/14, but as an improper fraction it’s 17/14. Other options would come from mis-scaling the second fraction or arithmetic mistakes in the addition.
