&lt;br /&gt;
&amp;#039;&amp;#039;Pentru cei &amp;lt;math&amp;gt;24&amp;lt;/math&amp;gt; de elevi ai unei clase se confecționează ținuta școlară, constând din sarafan pentru fete și veste pentru băieți. Pentru &amp;lt;math&amp;gt;8&amp;lt;/math&amp;gt; sarafane și &amp;lt;math&amp;gt;4&amp;lt;/math&amp;gt; veste sunt necesari &amp;lt;math&amp;gt;20&amp;lt;/math&amp;gt;m de stofă, iar pentru &amp;lt;math&amp;gt;10&amp;lt;/math&amp;gt; sarafane și &amp;lt;math&amp;gt;12&amp;lt;/math&amp;gt; veste sunt necesari &amp;lt;math&amp;gt;32&amp;lt;/math&amp;gt;m de stofă. Aflați câți metri de stofă sunt necesari pentru confecționarea ținutei școlare pentru toți elevii clasei, știind că numărul fetelor este cu &amp;lt;math&amp;gt;2&amp;lt;/math&amp;gt; mai mare decât cel al băieților.&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Soluție&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
I. Pentru determinarea numărului de fete și a numărului de băieți folosim metoda figurativă.&lt;br /&gt;
&lt;br /&gt;
Egalarea părților: 2 părți ... 24-2&lt;br /&gt;
1. Câți băieți sunt în clasă?&lt;br /&gt;
&amp;lt;math&amp;gt;(24-2) : 2 = 11 (băieți)&amp;lt;/math&amp;gt;&lt;br /&gt;
2.Câte fete sunt în clasă? &lt;br /&gt;
&amp;lt;math&amp;gt; 11+2=13(fete)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
II. Pentru determinarea cantității de stofă folosim metoda comparației.&lt;br /&gt;
&lt;br /&gt;
Datele problemei se pot sintetiza astfel:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; 8 \text{ sarafane } \ldots \ldots \ldots 4 \text{ veste } \ldots \ldots \ldots 20 \text{ metri de stofă }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; 10 \text{ sarafane } \ldots \ldots \ldots 12 \text{ veste } \ldots \ldots \ldots 32 \text{ metri de stofă }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Pentru a fi posibilă compararea cantităților este necesar să avem o cantitate comună, de exemplu &amp;lt;math&amp;gt;12&amp;lt;/math&amp;gt; veste, deci este necesar să considerăm prima grupare de trei ori și obținem&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; 24 \text{ sarafane } \ldots \ldots \ldots 12 \text{ veste } \ldots \ldots \ldots 60 \text{ metri de stofă }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; 10 \text{ sarafane } \ldots \ldots \ldots 12 \text{ veste } \ldots \ldots \ldots 32 \text{ metri de stofă }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Prin comparare deducem că &lt;br /&gt;
&amp;lt;math&amp;gt; 14 \text{ sarafane } \ldots \ldots \ldots  28 \text{ metri de stofă }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
3. Câți metri de stofă sunt necesari pentru confecționarea unui sarafan?&lt;br /&gt;
&amp;lt;math&amp;gt; 28 : 14 = 2 (m stof\u a)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
4. Câți metri de stofă sunt necesari pentru confecționarea unei veste?&lt;br /&gt;
&amp;lt;math&amp;gt; 32 - \left(10 \times 2) : 12 = 1 (m stof\u a)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
III.  Știm că s-au confecționat &amp;lt;math&amp;gt;13&amp;lt;/math&amp;gt; sarafane și &amp;lt;math&amp;gt;11&amp;lt;/math&amp;gt; veste, iar pentru un sarafan se folosesc &amp;lt;math&amp;gt;2&amp;lt;/math&amp;gt; metri de stofă și &amp;lt;math&amp;gt;1&amp;lt;/math&amp;gt; metru de stofă este necesar pentru confecținarea unei veste.&lt;br /&gt;
&lt;br /&gt;
5. Câți metri de stofă sunt necesari pentru confecționarea ținutei școlare pentru toți elevii clasei?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; 13 \times 2 + 11 \times 1 = 37 \text{ (m stof\u a)}&amp;lt;\math&amp;gt;&lt;/div&gt;</summary>
