Пошаговое объяснение:

7- 1/1=7-1=6

1- 1/1=1-1=0

2- 1/2=1 1/2

6- 2/2=6-1=5

5- 2/2=5-1=4

4- 2/3 =3 1/3

3/4+ 7/3=9/12+28/12=37/12=3 1/12

6- 3/8=5 5/8

5+ 8/4 =5 8/4=7

4- 4/5=3 1/5

Answer 2

It seems like you've written a series of mathematical expressions, but they are not entirely clear. The expressions contain fractions and operations such as addition and subtraction. I'll do my best to interpret and solve them step by step:

1. 7 - 1/1: Subtract 1 from 7. Result: 6.

2. 1 - 1/1: Subtract 1 from 1. Result: 0.

3. 2 - 1/2: Subtract 1/2 from 2. Result: 1.5.

4. 6 - 2/2: Subtract 2/2 (which is equal to 1) from 6. Result: 5.

5. 5 - 2/2: Subtract 2/2 (which is equal to 1) from 5. Result: 4.

6. 4 - 2/3: To subtract 2/3 from 4, we need to find a common denominator. The common denominator is 3. So, 4 - 2/3 is equal to (4 * 3)/3 - 2/3 = 12/3 - 2/3 = 10/3.

7. 3/4 + 7/3: To add fractions, we need a common denominator, which is 12. So, 3/4 + 7/3 = (3 * 3)/(4 * 3) + (7 * 4)/(3 * 4) = 9/12 + 28/12 = (9 + 28)/12 = 37/12.

8. 6 - 3/8: To subtract 3/8 from 6, we don't need a common denominator because 6 is equivalent to 48/8. So, 6 - 3/8 = 48/8 - 3/8 = 45/8.

9. 5 + 8/4: 8/4 is equal to 2, so 5 + 8/4 = 5 + 2 = 7.

10. 4 - 4/5: To subtract 4/5 from 4, we don't need a common denominator because 4 is equivalent to 20/5. So, 4 - 4/5 = 20/5 - 4/5 = 16/5.

If you have any more mathematical expressions or need further clarification, feel free to ask!
