Answer 2

To solve the expression -0.77 * (4/9) + (4/9) * 2.89 step by step without parentheses, we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Step 1: Evaluate the division

First, we need to evaluate the division expressions in the equation.

4 divided by 9 is equal to 0.4444 (repeating decimal).

So, the expression becomes: -0.77 * 0.4444 + 0.4444 * 2.89

Step 2: Perform the multiplications

Next, we perform the multiplications in the equation.

-0.77 multiplied by 0.4444 is equal to -0.3422.

0.4444 multiplied by 2.89 is equal to 1.2834.

So, the expression becomes: -0.3422 + 1.2834

Step 3: Perform the addition

Finally, we perform the addition in the equation.

-0.3422 plus 1.2834 is equal to 0.9412.

Therefore, the value of the expression -0.77 * (4/9) + (4/9) * 2.89, without parentheses, is approximately 0.9412.
