Question

{(9 supra 4 -2 supra 3 x 11 supra 6):[1 supra 5 x 3 intregi si 1 supra 3 +0,36(1)]-0,4}x 1 intreg si 2 supra 3

Answer 1

0,36(1)=(361-36)/900=325/900=13/36
{(9/4 -2/3 x 11/6):[1/5 x 3 intregi si 1/3 +0,36(1)]-0,4}x 1 intreg si 2/3 =
={(9/4 -22/18):[1/5 x 10/3 +13/36]-4/10}x 5/3 =
={(81-44)/18:[2/3 +13/36]-285}x 5/3 =
={37/18:[(24+13)/36]-2/5}x 5/3 =
=(37/18 ×36/37-2/5)x 5/3 =
=(2-2/5)x 5/3 =
=3/5x 5/3 =1
