Answer 3

To solve the given expression, we'll need to perform the operations step by step:

Step 1: Convert all mixed numbers to improper fractions. Step 2: Perform the operations from left to right, following the order of operations (PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).

Given expression: 2 2/7 - 2/3 + 3 5/7 - 1/3

Step 1: Convert mixed numbers to improper fractions: 2 2/7 = (2 * 7 + 2) / 7 = 16 / 7 3 5/7 = (3 * 7 + 5) / 7 = 26 / 7

Now, the expression becomes: 16/7 - 2/3 + 26/7 - 1/3

Step 2: Perform the operations:

16/7 - 2/3 + 26/7 - 1/3

To add fractions, the denominators must be the same. The common denominator for 7 and 3 is 21.

Rewrite each fraction with a denominator of 21:

(16/7) * (3/3) = 48/21 (2/3) * (7/7) = 14/21 (26/7) * (3/3) = 78/21 (1/3) * (7/7) = 7/21

Now, the expression becomes: 48/21 - 14/21 + 78/21 - 7/21

Combine the fractions with the same denominator:

(48 - 14 + 78 - 7) / 21 = 105/21

Finally, simplify the fraction:

105/21 = 5

So, the result of the expression is 5.
