va rog ex 5 ofer 10 puncte

[tex] \frac{1}{18 } + \frac{1}{9 } + \frac{1}{6} = \frac{1}{18} + \frac{2}{18} + \frac{3}{18} = \frac{6}{18} = \frac{1}{3} [/tex]
[tex] \frac{7}{36} - \frac{1}{18} + \frac{3}{4} = \frac{7}{36} - \frac{2}{36} + \frac{27}{36} = \frac{32}{36} = \frac{8}{9} [/tex]

c) 2×37-9×3-6×5/36=

74-27-30/36=17/36

d) 11-2×4+3×5-6×1/18=

11-8+15-6/18=12/18⁽⁶=2/3

Sper că te-am ajutat!
