Step-by-Step Solution

To solve this problem, we'll find out how much of the paper roll Danny used by adding the fractions representing the parts used for the book and notebook covers.

  • Step 1: Identify the fractions used.
  • Step 2: Determine the common denominator for the fractions 16 \frac{1}{6} and 23 \frac{2}{3} .
  • Step 3: Convert 23 \frac{2}{3} to the common denominator.
  • Step 4: Add the fractions.
  • Step 5: Simplify the result if needed.

Let's work through these steps:

Step 1: Danny used the fractions 16 \frac{1}{6} and 23 \frac{2}{3} .

Step 2: The denominators are 6 and 3. The least common denominator is 6.

Step 3: Convert 23 \frac{2}{3} to a fraction with a denominator of 6.

23=2×23×2=46 \frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4}{6}

Step 4: Add the fractions 16 \frac{1}{6} and 46 \frac{4}{6} .

16+46=1+46=56 \frac{1}{6} + \frac{4}{6} = \frac{1 + 4}{6} = \frac{5}{6}

Step 5: The fraction 56 \frac{5}{6} is already in its simplest form.

Therefore, Danny used 56 \frac{5}{6} of the paper roll in total.

The correct answer is 56 \frac{5}{6} .

Answer

56 \frac{5}{6}
