При операциях на числовых множествах за универсальное множество берут:

1.все целые числа
2.только множество натуральных чисел
3.всё множество действительных чисел​

Хм, интересное задание.

Кол-во символов в строке = 24

Кол-во букв "a" на английской раскладке = 8

Кол-во букв "s" = 8

Кол-во букв "d" = 8

"a" = "s" = "d"

"a" + "a" = 16

"a" + "s" = "s" + "a" = 16

"a" + "d" = "d" + "a" = 16

"s" + "s" = 16

"s" + "d" = "d" + "s" = 16

"d" + "d" = 16

"a" - "a" = 0

"a" - "s" = "s" - "a" = 0

"a" - "d" = "d" - "a" = 0

"s" - "s" = 0

"s" - "d" = "d" - "s" = 0

"d" - "d" = 0

"a" : "a" = 1

"a" : "s" = "s" : "a" = 1

"a" : "d" = "d" : "a" = 1

"s" : "s" = 1

"s" : "d" = "d" : "s" = 1

"d" : "d" = 1

"a" × "a" = 64

"a" × "s" = "s" × "a" = 64

"a" × "d" = "d" × "a" = 64

"s" × "s" = 64

"s" × "d" = "d" × "s" = 64

"d" × "d" = 64

Это задание было сложно понять. Фух...

1) 1/4-4 1/8=2 1/4-1/8=2 2/8-1/8=2 1/8

2) 1/8·4=17/8·4=17/2=8 1/2

3) 1/3:2 1/2= 10/3:5/2=10/3·2/5=4/3

4)2/1*3 1/4=2/1*13/4=13/2=6 1/2

(7/10-2/5)*(1/4+5/6):6 1/2

1) 7/10-2/5=(7-4)/10=3/10

2) 1/4+5/6= (3+10)/12=13/12

3) 3/10*13/12:13/2=1/20
