Answer 1

Răspuns:

a)3 b)9

Explicație pas cu pas:

a)

$( \frac{6} {12} + \frac{9}{12} + \frac{10}{12} ) + ( \frac{6}{12} + \frac{3}{12} + \frac{2}{12} ) = \frac{25}{12} + \frac{11}{12} = \frac{36}{12} = 36 \div 12 = 3$

b)

$(\frac{135}{90} + \frac{126}{90} + \frac{50}{90} ) + \frac{135}{90} + \frac{144}{90} + \frac{220}{90} ) = \frac{311}{90} + \frac{499}{90} = \frac{810}{90} = 810 \div 90 = 9$
