Answer 3

To add the mixed numbers, you first need to convert them to improper fractions. Then, you can add the fractions and the whole numbers separately. Let's go step by step:

Step 1: Convert the mixed numbers to improper fractions: 4 1/7 = (4 * 7 + 1) / 7 = 29/7 3 5/14 = (3 * 14 + 5) / 14 = 47/14

Step 2: Add the fractions: 29/7 + 47/14

To add fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of 7 and 14 is 14. So, we can rewrite the fractions with a common denominator of 14:

29/7 = (29/7) * (2/2) = 58/14 47/14 (already in the desired form)

Step 3: Add the fractions: 58/14 + 47/14 = (58 + 47) / 14 = 105/14

Step 4: Add the whole numbers: 12 + 105/14

To add a whole number and a fraction, we need to convert the whole number to a fraction with the same denominator as the fraction:

12 = 12/1

Step 5: Add the whole number and the fraction: 12/1 + 105/14

To add fractions, we need a common denominator. The least common multiple (LCM) of 1 and 14 is 14. So, we can rewrite the fractions with a common denominator of 14:

12/1 = (12/1) * (14/14) = 168/14 105/14 (already in the desired form)

Step 6: Add the fractions: 168/14 + 105/14 = (168 + 105) / 14 = 273/14

Therefore, the sum of 4 1/7, 12, and 3 5/14 is 273/14.
