Zepler [3.9K]

Answer:

The correct option is C. About 1 on the side with the 1 on top and 4 on the bottom yard.

Step-by-step explanation:

Consider the provided information.

Simone measures the width of one of cardboard strip as 1/2 yard.

The combined width of the cardboard strip:

\frac{1}{2} + \frac{5}{6}=\frac{8}{6}=1\frac{1}{3}

1\frac{1}{3} is closer to1\frac{1}{4} as compare to 1\frac{1}{2}

Hence, the correct option is C. About 1 on the side with the 1 on top and 4 on the bottom yard.
