Помогите пожалуйста!!! ❤️ ​

Answer 1

а)5/6 b + 3/10 b - 7/15 b =2/3 b

б)3 5/6 y - 2 5/12 y + 1 1/3 y=2 17/36y

Answer 2

Ответ:

а) 5/6b+3/10b-7/15b = 25/30b+9/30b-14/30b = 20/30b=2/3b

б) 3 5/6y-2 5/12y+1 1/3y = 3 10/12y-2 5/12y+1 4/12y = 2 9/12y = 2 3/4y

8* (5/8y - 2 3/4)=3

5/8y - 11/4 = 3/8

5/8y = 11/4+3/8

5/8y = 22/8+3/8=25/8

y = 25/8:5/8

y = 25*8/5*8 = 5
