Question

1) some as frações e simplifique quando for possivel

a) 3/2 + 6/5

b) 7/4 + 7/6

c) 4/3 + 1/9

d)3/4 + 5/6

e) 7/12 + 5/6 + 1/3

f)8/3 + 5/2 + 4/6

​

Answer 1

$a) \frac{3}{2} + \frac{6}{5} = \frac{15 + 12}{10} = \frac{27}{10}$

$b) \frac{7}{4} + \frac{7}{6} = \frac{21 + 14}{12} = \frac{35}{12}$

$c) \frac{4}{3} + \frac{1}{9} = \frac{12 + 1}{9} = \frac{13}{9}$

$d) \frac{3}{4} + \frac{5}{6} = \frac{9 + 10}{12} = \frac{19}{12}$

$e) \frac{7}{12} + \frac{5}{6 } + \frac{1}{3} = \frac{7 + 10 + 4}{12} = \frac{21}{12} = \frac{7}{4}$

$f) \frac{8}{3} + \frac{5}{2} + \frac{4}{6} = \frac{16 + 15 + 4}{6} = \frac{35}{6}$
