Comments

у тебя между 3 и 4 какой знак?

Answer 1

3  4\15-2  6\15 = 49/15-36/15 = 13/15
13/15 + 6  2/15 = 13/15+92/15 = 105/15
1  7\15+14\15 = 22/15+14/15 = 36/15
105/15-36/15 = 69/15 = 23/5 = 4  3/5 = 4.6

Answer 2

(3,4/15-2,6/15)+6,2/15-(1,7/15+14/15)=(34/150-26/150)+62/150-(17/150+14/15)=7/150+62/150-157/150=-88/150
