Verify if (5×3-4×2)/(2×4-3×5) = 0: Fraction Simplification Check

Question

Determine if the simplification below is correct:

53422435=0 \frac{5\cdot3-4\cdot2}{2\cdot4-3\cdot5}=0

Video Solution

Step-by-Step Solution

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:

53422435 \frac{5\cdot3-4\cdot2}{2\cdot4-3\cdot5}

First, let's calculate the numerator:

  • Calculate 53=155 \cdot 3 = 15.
  • Calculate 42=84 \cdot 2 = 8.
  • Subtract these results: 158=715 - 8 = 7.

The numerator simplifies to 77.

Next, we calculate the denominator:

  • Calculate 24=82 \cdot 4 = 8.
  • Calculate 35=153 \cdot 5 = 15.
  • Subtract these results: 815=78 - 15 = -7.

The denominator simplifies to 7-7.

Now, we perform the division:

77=1 \frac{7}{-7} = -1

Thus, the value of the original expression is 1-1, not 00, as stated in the problem.

Therefore, the statement that the original expression simplifies to 00 is false.

Hence, the correct answer to this problem is False.

Answer

False
