Answer 2

To evaluate the expression (-5+8)+(-0.36+(-0.64))-1 2/3, we need to follow the order of operations (also known as PEMDAS/BODMAS) and simplify it step by step.

Step 1: Simplify within parentheses and brackets first. (-5+8) = 3 (-0.36+(-0.64)) = -1

The expression now becomes: 3 + (-1) - 1 2/3

Step 2: Convert the mixed number 1 2/3 to an improper fraction. 1 2/3 = (3*1 + 2)/3 = 5/3

The expression now becomes: 3 + (-1) - 5/3

Step 3: Perform addition and subtraction from left to right. 3 + (-1) = 2

The expression now becomes: 2 - 5/3

Step 4: Subtract the fractions. To subtract fractions, we need a common denominator. The common denominator for 1 and 3 is 3. So, we rewrite 2 as 6/3.

6/3 - 5/3 = (6 - 5)/3 = 1/3

Therefore, the simplified value of the expression (-5+8)+(-0.36+(-0.64))-1 2/3 is 1/3.
