Question

32 Opera i simplifica: 5/6 - 1/12 | 13/10 - 2/5 | 12/9 - 5/6​

Answer 1

Explicación paso a paso:

$\frac{5}{6} - \frac{1}{12} = m.c.m(6 \: y \: 12) = 12 = \frac{10}{12} - \frac{1}{12} = \frac{9}{12} = \frac{3}{4}$

$\frac{13}{10} - \frac{2}{5} = m.c.m \: (10 \: y \: 5) = 10 = \frac{13}{10} - \frac{4}{10} = \frac{9}{10}$

$\frac{12}{9} - \frac{5}{6} = \: m \:cm \: (9 \: y \: 6) = 36 = \frac{48}{36} - \frac{30}{36} = \frac{18}{36} = \frac{6}{12} = \frac{3}{6} = \frac{1}{2}$
