Step-by-step explanation:
The first thing to do is to pass the mixed fractions to integers, then a fraction subtraction is required to see the difference between the length of the two lines.
To convert a mixed fraction into improper, follow these steps:
-Multiply the whole part by the denominator.
-Add it to the numerator.
-Then write the result above the denominator.
Now, following the steps already mentioned, the exercise is as follows:
![\begin{gathered} 9\text{ }(1)/(3)=(28)/(3) \\ 3(1)/(2)=(7)/(2) \\ \text{Now }we\text{ must substract}\colon \\ (28)/(3)-(7)/(2)=(56-21)/(6)=(35)/(6) \\ \\ In\text{ fraction is longer }(35)/(6)\text{ which is the same in decimal 5.8} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/hdatw6x8ejkp3phw4n1zq9au3oeujq34qd.png)
