    Step-by-step walkthrough

    Choose a solution method

    Method #1Direct Approach

    Step 1: Recall the definition of numerator and denominator

    In a fraction , the numerator is the top number and the denominator is the bottom number .

    Step 2: Apply the definition to $\frac{5}{8}$

    Here, (top) and (bottom). So the numerator is 5 and the denominator is 8.

    Step 3: Choose the correct answer

    The correct answer is Numerator is 5, denominator is 8.

    Method #2Process of Elimination

    Step 1: Identify what is being asked

    The question asks which option correctly names the numerator (top number) and denominator (bottom number) of .

    Step 2: Eliminate 'Numerator is 8, denominator is 5'

    This option swaps the numerator and denominator. The number on top is 5, not 8, so this is incorrect.

    Step 3: Eliminate 'Numerator is 5, denominator is 5' and 'Numerator is 8, denominator is 8'

    Both of these options repeat the same number for both parts of the fraction, which makes no sense for where the two numbers are different.

    Step 4: Select the correct answer

    The only correct option is Numerator is 5, denominator is 8, which correctly identifies 5 as the top number and 8 as the bottom number.
