Answer :
EXPLANATION:
In the exercise we can see that it is a division of fractions because we need to know exactly how much length corresponds to each panel, for that we must divide the mixed fraction between the 7 panels.
Now to be able to do a correct division of fractions it is necessary that the mixed fraction becomes an improper fraction and the integer 7 must be converted into a fraction.
Now following the steps already mentioned, the exercise will be as follows:
[tex]\begin{gathered} first\text{ convert }mixed\text{ fraction to improper:} \\ 12\frac{5}{6}=\frac{77}{6} \\ \text{Now }we\text{ must convert }the\text{ 7 to a fraction }for\text{ that we }add\text{ the numer 1 } \\ to\text{ the denominator }; \\ \frac{7}{1} \\ Now\text{ we can divide }both\text{ fractions} \\ \frac{77}{6}\colon\frac{7}{1};to\text{ divide the numerator is multiplied }witch\text{ the second denominator} \\ \frac{77}{6}\times\frac{7}{1}=\frac{77}{42}=1.83\text{ }for\text{ each panel} \end{gathered}[/tex]
