Answer 1

3 5/7-1 11/21+2 5/14 = 4 23/423 5/7 + 2 5/14 = 3 10/14 + 2 5/14 = 5 15/14 = 6 1/14
6 1/14 - 1 11/21 =  6 6/84 - 1 44/84 = 5 90/84 - 1 44/84 = 4 46/84 = 4 23/42

Answer 2

To add or subtract mixed numbers, you should first find a common denominator and then perform the operation. Let's subtract and add the mixed numbers:

3 5/7 - 1 11/21 + 2 5/14

Step 1: Find a common denominator. In this case, we can use 42, which is the least common multiple of 7, 21, and 14.

Step 2: Convert the mixed numbers to fractions with the common denominator.

3 5/7 = (3 * 42/7) + (5/7 * 42/7) = 18/7 + 30/42 1 11/21 = (1 * 42/21) + (11/21 * 42/21) = 2/1 + 462/21 2 5/14 = (2 * 42/14) + (5/14 * 42/14) = 12/7 + 210/14

Step 3: Perform the calculations with the common denominator:

(18/7 - 2/1 + 12/7) = (18/7 + 12/7 - 2/1)

Now, add the fractions:

(18/7 + 12/7 - 2/1) = (30/7 - 2/1)

Step 4: Subtract the fractions:

(30/7 - 2/1) = (30/7 - 14/7)

Now, subtract the fractions:

(30/7 - 14/7) = 16/7

So, 3 5/7 - 1 11/21 + 2 5/14 is equal to 16/7 as an improper fraction.
