con procedimiento por favor lo nesesito

Answer 1

Explicación paso a paso:

$\frac{12 } {3} + \frac{4}{9} = \frac{(12 \times 9) + (3 \times 4)}{3 \times 9} = \frac{108 + 12}{27} = \frac{120}{27}$

$\frac{8}{4} + \frac{3}{10} = \frac{(8 \times 10) + (3 \times 4)}{4 \times 10} = \frac{80 + 12}{40} = \frac{92}{40}$

$\frac{6}{8} + \frac{4}{3} = \frac{(6 \times 3) + (4 \times 8)}{8 \times 3} = \frac{18 + 32}{24} = \frac{50}{24}$

$\frac{2}{5} + \frac{3}{2} = \frac{(2 \times 2) + (3 \times 5)}{5 \times 2} = \frac{4 + 15}{10} = \frac{19}{10}$
