27•76+76:45

To solve this arithmetic expression, we need to follow the correct order of operations, which can be remembered by the acronym PEMDAS, standing for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Since there are no parentheses, exponents, or multiplication operations in the provided expression, we start with division, followed by addition.

The expression is: 27•76 + 76 ÷ 45

First, we do the division part: 76 ÷ 45 = 1.6888888888888889 (rounded off to its decimal form)

Now we add the result of the division to the first part of the expression: 27•76 + 1.6888888888888889

Multiplication is the next step: 27 * 76 = 2052

Finally, we add the two results together: 2052 + 1.6888888888888889 = 2053.6888888888889

So the final answer, rounded to two decimal places, is approximately 2053.69.
