Identifying Meaningless Expressions (ME) in Mathematical Statements

To solve this problem, we'll follow these steps:

• Step 1: Identify the operations present in each expression.
• Step 2: Determine if any expression involves division by zero.

Now, let's work through each step:
Step 1: The expression choices are $\frac{700}{0}$ and $\frac{0}{700}$.
Step 2: Analyze each expression:

• Expression $\frac{700}{0}$: Divides 700 by 0. Division by zero is undefined in mathematics, making this a meaningless expression.
• Expression $\frac{0}{700}$: Divides 0 by 700. This results in 0, which is a defined mathematical operation and therefore not meaningless.

Therefore, the expression that is identified as a meaningless expression is $\frac{700}{0}$.
