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

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.
