Evaluating the Expression: 4(1/2x5x4)
When dealing with mathematical expressions that involve multiple operations, it's essential to follow the order of operations (PEMDAS) to arrive at the correct answer. In this article, we'll walk through the step-by-step evaluation of the expression 4(1/2x5x4).
Step 1: Evaluate the Expression Inside the Parentheses
First, let's focus on the expression inside the parentheses: 1/2x5x4. To evaluate this expression, we need to follow the order of operations.
Evaluate the Fraction: 1/2
The fraction 1/2 can be simplified to 0.5.
Multiply 0.5 by 5
0.5 × 5 = 2.5
Multiply 2.5 by 4
2.5 × 4 = 10
So, the expression inside the parentheses evaluates to 10.
Step 2: Multiply 4 by the Result
Now that we have evaluated the expression inside the parentheses, we can multiply 4 by the result:
4 × 10 = 40
Therefore, the final answer is 40.
Conclusion
By following the order of operations and evaluating the expression step-by-step, we arrived at the correct answer: 4(1/2x5x4) = 40.
