\section{Simplifications de fractions}
\begin{itemize}
\item Trouver le numérateur quand le dénominateur augmente
%- set a,b,ans,c = random_list(["{a}", "{b}", "{a*c}", "{b*c}"], conditions = ["a != b"], min_max=(2, 10))
\begin{align*}
\dfrac{\Var{a}}{\Var{b}} = \dfrac{\ldots}{\Var{c}}
\end{align*}
Solution
\begin{align*}
\dfrac{\Var{a}}{\Var{b}} = \dfrac{\Var{ans}}{\Var{c}}
\end{align*}
\item Trouver le numérateur quand le dénominateur diminue
\Block{set a,b,ans,c = random_list(["{a*c}", "{b*c}", "{a}", "{b}"], conditions = ["a != b"], min_max=(2, 10))}
\begin{align*}
\dfrac{\Var{a}}{\Var{b}} = \dfrac{\cdots}{\Var{c}}
\end{align*}
Solution
\begin{align*}
\dfrac{\Var{a}}{\Var{b}} = \dfrac{\Var{ans}}{\Var{c}}
\end{align*}
Explications \Var{type(a)} -- \Var{type(b)}
set f = Expression.from_str(str(int(a)) + " / " + str(int(b)))
\begin{align*}
\texttt{f.simplify().explain()|join('=')}
\end{align*}
\end{itemize}
\section{Ajouts de fractions}
\begin{itemize}
\item Fraction avec le même dénominateur
\Block{set e = Expression.random("{a} / {b} + {c} / {b}", ["b > 1"], min_max=(1, 10))}
\begin{align*}
A = \Var{e}
\end{align*}
Solution
\begin{align*}
\Var{e.simplify().explain() | join('=')}
\end{align*}
\item Fraction avec un denominateur multiple de l'autre
\Block{set e = Expression.random("{a} / {b} + {c} / {b*d}", ["b > 1","d > 1"], min_max=(1, 10))}
\begin{align*}
A = \Var{e}
\end{align*}
Solution
\begin{align*}
\Var{e.simplify().explain() | join('=')}
\end{align*}
\item Une fraction et un entier
\Block{set e = Expression.random("{a} / {b} + {c}", ["b > 1"], min_max=(1, 10))}
\begin{align*}
A = \Var{e}
\end{align*}
Solution
\begin{align*}
\Var{e.simplify().explain() | join('=')}
\end{align*}
\item Une fraction et un entier
\Block{set e = Expression.random("{c} + {a} / {b}", ["b > 1"], min_max=(1, 10))}
\begin{align*}
A = \Var{e}
\end{align*}
Solution
\begin{align*}
\Var{e.simplify().explain() | join('=')}
\end{align*}
\end{itemize}
\section{Multiplications de fractions}
\begin{itemize}
\item Une fraction et un entier
\Block{set e = Expression.random("{c} * {a} / {b}", min_max=(2, 10))}
\begin{align*}
A = \Var{e}
\end{align*}
Solution
\begin{align*}
\Var{e.simplify().explain() | join('=')}
\end{align*}
\item Fraction avec des dénominateurs quelconques
\Block{set e = Expression.random("{a} / {b} * {c} / {d}", ["b > 1","d > 1"], min_max=(1, 10))}
\begin{align*}
A = \Var{e}
\end{align*}
Solution
\begin{align*}
\Var{e.simplify().explain() | join('=')}
\end{align*}
\end{itemize}
