Question

Rezolvati: (1/4+2/3):11/3+27/2×(2/9-1/6)

Answer 1

(1/4 + 2/3)/11/3+27/2*(2/9-1/6)
(3/12 + 8/12)/11/3+27/2(4/18 - 3/18)
11/12 /11 /3 + 27/2*1/18
$\frac{11}{12} / \frac{11}{3}+ \frac{27}{2} * \frac{1}{18} = \frac{11}{12} * \frac{3}{11} + \frac{27}{36} = \frac{33}{132} + \frac{27}{36} = \frac{1188}{4752} + \frac{3564}{4752} = \frac{4752}{4752} = 1$
