Answer 1

Calculating the Expression (3.9-5.38) : 0.37 * (-14 + 4/5 + 0.45) * (-0.4)

To solve the given expression, we can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

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

Step 1: Inside the parentheses: - (-14 + 4/5 + 0.45) = -14 + 0.8 + 0.45 = -14 + 1.25 = -12.75

Now, we can substitute the result back into the original expression:

Step 2: Calculate the expression (3.9 - 5.38) : 0.37 * (-12.75) * (-0.4)

Step 3: Calculate (3.9 - 5.38) = -1.48

Step 4: Substitute the result into the expression: -1.48 : 0.37 * (-12.75) * (-0.4)

Step 5: Calculate -1.48 : 0.37 = -4 - (-4) * (-12.75) * (-0.4) = 204

So, the value of the given expression (3.9-5.38) : 0.37 * (-14 + 4/5 + 0.45) * (-0.4) is 204.
