Question

a 12/5 +4/2= b 5/12+8/3 -1/4=

Answer 1

$A) \frac{12}{5} + \frac{4}{2}\\\\ MMC = 10\\\\ \frac{24}{10} + \frac{20}{10} = \frac{44}{10} :^2 => \frac{22}{5}$

$B) \frac{5}{12} + \frac{8}{3} - \frac{1}{4}\\\\ MMC = 12\\\\ \frac{5}{12} + \frac{32}{12} - \frac{3}{12} = \frac{34}{12} :^2 => \frac{17}{6}$
