Determine if the simplification below is correct:
To determine if the given mathematical simplification is correct, we must evaluate both the numerator and the denominator separately and then divide the results. Let's work through this step by step.
The expression we are examining is:
First, let's calculate the numerator:
The numerator simplifies to .
Next, we calculate the denominator:
The denominator simplifies to .
Now, we perform the division:
Thus, the value of the original expression is , not , as stated in the problem.
Therefore, the statement that the original expression simplifies to is false.
Hence, the correct answer to this problem is False.
False
Determine if the simplification shown below is correct:
\( \frac{7}{7\cdot8}=8 \)
When you calculate , you're subtracting a larger number from a smaller one, which always gives a negative result. This is perfectly normal in math!
A fraction equals zero only when the numerator is zero and the denominator is not zero. Since our numerator is 7 (not 0), this fraction cannot equal zero.
Dividing a positive number by a negative number always gives a negative result. So , not zero.
Yes, always simplify first! In this case, simplifies to , making it clear the answer is not zero.
Calculators are helpful, but make sure you use parentheses correctly! Enter it as (5×3-4×2)÷(2×4-3×5) to get the right answer of -1.
