a) [tex]\frac{1}{6} +\frac{1}{2} +\frac{1}{4} +\frac{1}{3} +x=2[/tex]
mcm=12
[tex]\frac{2+6+3+4}{12}+x=2[/tex]
[tex]\frac{15}{12} +x=2[/tex]
[tex]x=2-\frac{15}{12}[/tex]
[tex]x=\frac{24-15}{12}[/tex]
[tex]x=\frac{9}{12}[/tex]
[tex]x=\frac{3}{4}m[/tex]
b) hay un error de unidades, debería ser 25,8cm no m.
[tex]5,5+3,4+2,5+2+6+1+3+x=25,8[/tex]
[tex]23,4+x=25,8[/tex]
[tex]x=25,8-23,4[/tex]
[tex]x=2.4cm[/tex]
