The length of the rope Kurt started with is 13 1/3 inches
<h3>Calculating lengths </h3>
From the question, we are to determine the total length of the rope
From the given information,
The first piece was 4 4/5 inches long
and
The second piece was 8 1/2 inches long
Then,
The length of the rope Kurt started with will be
4 4/5 + 8 1/2
![4\frac{4}{5} + 8\frac{1}{2}](https://tex.z-dn.net/?f=4%5Cfrac%7B4%7D%7B5%7D%20%2B%208%5Cfrac%7B1%7D%7B2%7D)
First, convert the fractions into improper fractions
![\frac{24}{5} + \frac{17}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B5%7D%20%2B%20%5Cfrac%7B17%7D%7B2%7D)
The Lowest common multiple (LCM) of the denominators is 10.
Then, we get
![\frac{(2\times 24) + (5 \times 17)}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B%282%5Ctimes%2024%29%20%2B%20%285%20%5Ctimes%2017%29%7D%7B10%7D)
= ![\frac{48 + 85}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B48%20%2B%2085%7D%7B10%7D)
= ![\frac{133}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B133%7D%7B10%7D)
= ![13 \frac{1}{3}](https://tex.z-dn.net/?f=13%20%5Cfrac%7B1%7D%7B3%7D)
Hence, the length of the rope Kurt started with is 13 1/3 inches.
