Answer 2

Solving the Expression

To solve the given expression 9⅘ ÷ (79⅜ - 1⅛ - 77½ + 2⅜) × (37⅘ - 36⅘ + 4/5), we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, let's simplify the expression within the parentheses:

79⅜ - 1⅛ - 77½ + 2⅜ = 79⅜ - 1⅛ - 77½ + 2⅜ = 79.875 - 1.125 - 77.5 + 2.375 = 3.625

So, the expression becomes:

9⅘ ÷ 3.625 × (37⅘ - 36⅘ + 4/5)

Now, let's simplify the expression within the parentheses:

37⅘ - 36⅘ + 4/5 = 37.8 - 36.8 + 0.8 = 1

So, the expression becomes:

9⅘ ÷ 3.625 × 1

Now, we can perform the division:

9⅘ ÷ 3.625 = 9.8 ÷ 3.625 = 2.68965517241

Finally, we multiply the result by 1:

2.68965517241 × 1 = 2.68965517241

Therefore, the solution to the given expression is 2.68965517241.

Explanation

The given expression involves a combination of addition, subtraction, multiplication, and division of mixed numbers and fractions. By following the order of operations and simplifying the expression within the parentheses first, we were able to solve the expression step by step to arrive at the final result of 2.68965517241.
