DAU COROANA!!

Answer 1

$1). \frac{9}{18}+ \frac{5}{36} = \frac{18}{36} + \frac{5}{36} = \frac{23}{36} \\ \\ 2). \frac{7}{180} + \frac{7}{84} + \frac{11}{210} = \frac{49}{1260} + \frac{105}{1260} + \frac{66}{1260} = \frac{220}{1260} = \frac{110}{630} = \frac{55}{315} = \frac{11}{63} \\ \\ 3). \frac{5}{32} + \frac{7}{96} + \frac{13}{288} = \frac{45}{288} + \frac{21}{288} + \frac{13}{288} = \frac{79}{288}$

$4). \frac{19}{5} + \frac{1}{36} + \frac{1}{40} = \frac{1368}{360} + \frac{10}{360} + \frac{9}{360} = \frac{1387}{360}$
