Question

Resolva as seguintes Adições de frações
1/6 + 2/3
1/2 + 2/3
4/9 + 5/9
5/8 + 5/6
9/10 + 1/8
6/9 + 5/6

Answer 1

$\frac{1}{6} + \frac{2}{3} = \frac{1}{6} + \frac{4}{6} = \frac{5}{6} \\ \\ \frac{1}{2} + \frac{2}{3} = \frac{3}{6} + \frac{4}{6} = \frac{7}{6} \\ \\ \frac{4}{9} + \frac{5}{9} = \frac{9}{9} = 1 \\ \\ \frac{5}{8} + \frac{5}{6} = \frac{15}{24} + \frac{20}{24} = \frac{35}{24} \\ \\ \frac{9}{10} + \frac{1}{8} = \frac{36}{40} + \frac{5}{40} = \frac{41}{40} \\ \\ \frac{6}{9} + \frac{5}{6} = \frac{12}{18} + \frac{15}{18} = \frac{27}{18} = \frac{3}{2}$

Answer 2

Fazemos o MMC
a) 1/6 + 4/6 = 5/6
b) 3/6 + 4/6 = 7/6
c) 4/9 + 5/9 = 9/9 = 1
d) 15/24 + 20/24 = 35/24
e) 36/40 + 5/40 = 41/40
f) 12/18 + 15/18 = 27/18
