Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

1. Start by simplifying the multiplication and division within the expression: 5/6 + 1 2/7 * 5 5/6 - 4 3/4

   First, deal with the multiplication and division from left to right:

   5/6 + 1 2/7 * 5 5/6 - 4 3/4 = 5/6 + 15/7 * 35/6 - 19/4

   Now, find the products and simplify:

   5/6 + (15/7) * (35/6) - 19/4 = 5/6 + (525/42) * (35/6) - 19/4 = 5/6 + (25/2) * (35/6) - 19/4 = 5/6 + (25 * 35) / (2 * 6) - 19/4 = 5/6 + (875/12) - 19/4

2. Now, find a common denominator so you can add and subtract the fractions:

   The common denominator for 6, 12, and 4 is 12.

   5/6 + (875/12) - 19/4 = (10/12) + (875/12) - (57/12)

3. Add and subtract the fractions:

   (10/12) + (875/12) - (57/12) = (10 + 875 - 57) / 12 = 828/12

4. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 12:

   828/12 = (828 ÷ 12) / (12 ÷ 12) = 69/1 = 69

So, the value of the expression is 69.
