<div style="text-align: justify;"><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;">Solución:<br /><br />Para poder calcular la expresión equivalente a la constante de proporcionalidad conjunta entre tres variables, debemos conocer la relación de una de ellas con las otras. <br /><br />Luego de reconocer cuáles son directas y cuáles inversas, construimos la expresión, la que corresponde a una fracción, cuyo:<br /></span></font></span> <ul> <li><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;">Numerador: contiene a la primera variable multiplicada por las variables que sean inversas con esta.</span></font></span></li> <li><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;">Denominador: contiene al producto entre las variables que sean directas con la primera variable. De no haber variabilidad directa, el denominador seria 1, y por lo tanto desaparece.<br /></span></font></span></li> </ul><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;">En este caso: </span></font></span><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;">#TEXTOPREG1<span style="font-weight: bold;"> #VAR1 </span>(es decir,<span style="font-weight: bold;"> </span><span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mi»#COMP1«/mi»«/math»</span>)es #TEXTO1 proporcional a #TEXTOPREG2<span style="font-weight: bold;"> #VAR2 </span>(es decir,<span style="font-weight: bold;"> </span><span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mi»#COMP2«/mi»«/math»</span>) #TEXTO2 proporcional a #TEXTOPREG3<span style="font-weight: bold;"> #VAR3 </span>(es decir,<span style="font-weight: bold;"> </span><span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mi»#COMP3«/mi»«/math»</span>), así:<br /><br /></span></font></span> <div style="text-align: center;"><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;"><span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mi»#sol«/mi»«/math»</span></span></font></span><br /><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;"></span></font></span></div><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;"></span></font></span><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;"></span></font></span><span style="font-style: italic;"><font size="4"><span style="font-family: times new roman,times,serif;"></span></font></span></div>
