Answer 2

To solve the expression -0.168:1.6+0.2 ×(0.45- 4/5), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

Step 1: Solve the expression inside the parentheses. 0.45 - 4/5 = 0.45 - 0.8 = -0.35

Now the expression becomes: -0.168:1.6+0.2 × (-0.35)

Step 2: Perform the multiplication/division from left to right. 0.2 × (-0.35) = -0.07

Now the expression becomes: -0.168:1.6 - 0.07

Step 3: Perform the division. -0.168 ÷ 1.6 = -0.105

Now the expression becomes: -0.105 - 0.07

Step 4: Perform the subtraction. -0.105 - 0.07 = -0.175

Therefore, the value of the expression -0.168:1.6+0.2 × (0.45- 4/5) is -0.175.
