Question

va rog frumos pas cu pas​

Answer 1

a)

$\frac{1}{18} + \frac{1}{9} + \frac{1}{6}$

$\frac{1 + 2 + 3}{18}$

$\frac{6}{18}$

$\frac{1}{3}$

b)

$\frac{7}{36} - \frac{1}{18} + \frac{3}{4}$

$\frac{7 - 2 + 27}{36}$

$\frac{32}{36}$

$\frac{8}{9}$

c)

$\frac{37}{18} - \frac{3}{4} - \frac{5}{6}$

$\frac{74 - 27 - 30}{36}$

$\frac{17}{36}$

d)

$\frac{11}{18} - \frac{4}{9} - \frac{5}{6} - \frac{1}{3}$

$\frac{11 - 8 - 15 - 6}{18}$

$\frac{ - 18}{18}$

$- \frac{18}{18}$

$- 1$
