Explicación paso a paso:
[tex]B = \frac{\frac{1}{9} }{\frac{3}{5} } + \frac{\frac{1}{2} }{\frac{6}{3} } + 10\\\\B = \frac{5.1}{3.9} + \frac{3.1}{6.2} + 10\\\\B = \frac{5}{27} + \frac{3}{12} + 10\\\\B.27.12 = \frac{5}{27} . 27.12 + \frac{3}{12} .27.12 + 10.27.12\\\\27.12.B = 60 + 81 + 120.27\\\\27.12B = 141 + 3 240\\\\27.12B = 3 381\\\\B = \frac{3381}{27.12} \\\\B = \frac{3381}{324}\\\\B = \frac{1127}{108}[/tex]
