(0,5)² =(1/2)²=1/4
0,(6) = 6/9=2/3
0,375 = 375/1000 = 3/8
Ex. devine:
(1/4)/(2/3) + 1- (22/7) - 3/8 =(1/4)·(3/2) + 1 - (22/7) - 3/8 = 3/8+1- (22/7) - 3/8 =
=1 - 22/7 = 7/7 -22/7

[tex]\dfrac{3^{10}}{14^5} \cdot \dfrac{28^4}{3^8}:\dfrac{2^6\cdot3^2}{7^2} =\dfrac{3^{10}}{2^5\cdot7^5}\cdot\dfrac{2^8\cdot7^4}{3^8}\cdot\dfrac{7^2}{2^6\cdot3^2}=\dfrac{7}{8} [/tex]
