Evaluating the Expression: 1/3 × (9/4 × 8) - 2
In this article, we will evaluate the given expression: 1/3 × (9/4 × 8) - 2. To solve this expression, we need to follow the order of operations (PEMDAS):
Step 1: Evaluate the expression inside the parentheses
First, let's evaluate the expression inside the parentheses: 9/4 × 8.
9/4 × 8 = ?
To multiply a fraction by a whole number, we can multiply the numerator (9) by the whole number (8) and keep the same denominator (4).
9/4 × 8 = 72/4
Now, we can simplify the fraction:
72/4 = 18
So, the expression inside the parentheses is equal to 18.
Step 2: Evaluate the expression outside the parentheses
Now, let's evaluate the expression outside the parentheses: 1/3 × 18 - 2.
1/3 × 18 = ?
To multiply a fraction by a whole number, we can multiply the numerator (1) by the whole number (18) and keep the same denominator (3).
1/3 × 18 = 18/3
Now, we can simplify the fraction:
18/3 = 6
So, the expression 1/3 × 18 is equal to 6.
Step 3: Subtract 2 from the result
Finally, let's subtract 2 from the result:
6 - 2 = ?
6 - 2 = 4
Therefore, the final answer is:
1/3 × (9/4 × 8) - 2 = 4
