Quizplus · Accepted Answer

To find the total width of the scarf, add the widths of the individual stripes: $2 + 2 \frac{4}{5} + 5 \frac{2}{3}$ inches. Convert mixed numbers to improper fractions to simplify: $2 + \frac{14}{5} + \frac{17}{3}$ inches. Find a common denominator (15) and add: $\frac{30}{15} + \frac{42}{15} + \frac{85}{15} = \frac{157}{15}$ inches, which simplifies to $10 \frac{7}{15}$ inches.
