Помогите быстрее, дам лучшый ответ

Answer 1

1) 6 1/15+1 8/15=(6+1)+(1/15+8/15)=7 9/15
2) 8-4 2/15=7 15/15-4 2/15=(7-2)+(15/15-2/15)=5 13/15
7 9/15 -5 13/15=(9-5)+(9/15-13/15)=4 4/15

1) 3 1/9-2 4/9=(3-2)+(1/9-4/9)=1 1/3
2) 1 1/3+5/9=1+(1/3+5/9)=1 8/9
3) 5 2/9-1 8/9=(5-1) 1 (2/9-8/9)=4 2/3

Answer 2

(6(1/5)+1(8/15))-(8-4(2/15)=7(9/15)-(8-4(2/15))=7(9/15)-3(13/15)=6(24/15)-3(13/15)=3(11/15)
5(2/9)-(3(1/9)-2(4/9))+5/9=4(2/9)+5/9=4(7/9)
