5 1/3-2 3/7

To subtract 5 1/3 from 2 3/7, you'll first need to convert both numbers to the same denominator.

Step 1: Convert the mixed numbers to improper fractions:
5 1/3 = (5 * 3 + 1) / 3 = 16/3
2 3/7 = (2 * 7 + 3) / 7 = 17/7

Step 2: Find a common denominator for the fractions, which is the least common multiple (LCM) of the denominators 3 and 7. The LCM of 3 and 7 is 21.

Step 3: Convert the fractions to have a denominator of 21:
16/3 = (16 * 7) / (3 * 7) = 112/21
17/7 = (17 * 3) / (7 * 3) = 51/21

Now, you can subtract the fractions:
112/21 - 51/21 = (112 - 51) / 21 = 61/21

Therefore, 5 1/3 - 2 3/7 is equal to 61/21.
