How do you calculate the sum of mixed numbers 6 1/5 and 3 1/4?

• A. 10
• B. 9 9/20
• C. 8 1/5
• D. 9 3/4

Answer: (B)

To calculate the sum of the mixed numbers 6 1/5 and 3 1/4, it is important to convert each mixed number into an improper fraction first. For 6 1/5: - Convert it to an improper fraction: - Multiply the whole number (6) by the denominator (5): 6 * 5 = 30. - Then add the numerator (1): 30 + 1 = 31. - So, 6 1/5 becomes 31/5. For 3 1/4: - Similarly, convert it to an improper fraction: - Multiply the whole number (3) by the denominator (4): 3 * 4 = 12. - Then add the numerator (1): 12 + 1 = 13. - Thus, 3 1/4 becomes 13/4. Next, to sum these two fractions, we need to find a common denominator. The least common denominator (LCD) of 5 and 4 is 20. Now, convert each improper fraction: - For 31/5, multiply both the numerator and denominator by 4: - (

To calculate the sum of the mixed numbers 6 1/5 and 3 1/4, it is important to convert each mixed number into an improper fraction first.

For 6 1/5:

• Convert it to an improper fraction:

• Multiply the whole number (6) by the denominator (5): 6 * 5 = 30.

• Then add the numerator (1): 30 + 1 = 31.

• So, 6 1/5 becomes 31/5.

For 3 1/4:

• Similarly, convert it to an improper fraction:

• Multiply the whole number (3) by the denominator (4): 3 * 4 = 12.

• Then add the numerator (1): 12 + 1 = 13.

• Thus, 3 1/4 becomes 13/4.

Next, to sum these two fractions, we need to find a common denominator. The least common denominator (LCD) of 5 and 4 is 20.

Now, convert each improper fraction:

• For 31/5, multiply both the numerator and denominator by 4:

• (
