Answer 1

1)1/3-(3/5)=5/15-(9/15)=-4/15
2)-3/7-(+4/7)=-7/7=-1
3)-1/9-(+2/9)=-3/9=-1/3

Answer 2

Вычитания:

1) 1/3 - (3/5)

To subtract fractions, we need to find a common denominator. In this case, the common denominator is 15.

1/3 can be written as 5/15, and 3/5 can be written as 9/15.

So, the subtraction becomes:

5/15 - 9/15 = -4/15

Therefore, the result of the subtraction 1/3 - (3/5) is -4/15.

2) -3/7 - (+4/7)

Since the denominators are the same, we can directly subtract the numerators.

-3/7 - (+4/7) = -7/7 = -1

Therefore, the result of the subtraction -3/7 - (+4/7) is -1.

3) -1/9 - (+2/9)

Since the denominators are the same, we can directly subtract the numerators.

-1/9 - (+2/9) = -3/9 = -1/3

Therefore, the result of the subtraction -1/9 - (+2/9) is -1/3.

I hope this helps! Let me know if you have any further questions.
