Answer 1

Ответ:

5 7/15-2 3/15- 13/15=3 4/15-13/15=2 19/15-13/15=2 6/15

9 1/7-(3 4/7+2 6/7)=9  1/7 - 6 3/7=8 8/7-6 3/7=2 5/7

(7 -3 3/10) +2 9/10=3 7/10+2 9/10=6 6/10

Answer 2

To solve these equations step by step, let's break them down:

1. 5 7/15 - 2 3/15 - 13/15 = ?

First, subtract the fractions:

7/15 - 3/15 = 4/15

Now, subtract the whole numbers and the remaining fraction:

5 - 2 - 13/15 = 3 - 13/15 = 2 2/15

So, 5 7/15 - 2 3/15 - 13/15 = 2 2/15.

2. 9 1/7 - (3 4/7 + 2 6/7) = ?

First, add the fractions inside the parentheses:

4/7 + 6/7 = 10/7

Now, subtract this sum from 3 4/7:

3 4/7 - 10/7 = 3 - 1 + 3/7 = 2 3/7

Now, subtract this result from 9 1/7:

9 1/7 - 2 3/7 = 7 + 4/7 = 7 4/7

So, 9 1/7 - (3 4/7 + 2 6/7) = 7 4/7.

3. (7 - 3 3/10) + 2 9/10 = ?

First, subtract the fractions:

3/10 - 3/10 = 0

Now, subtract the whole numbers and add the remaining fraction:

7 - 0 + 2 9/10 = 7 + 2 9/10 = 9 9/10

So, (7 - 3 3/10) + 2 9/10 = 9 9/10.

In summary:

1. 5 7/15 - 2 3/15 - 13/15 = 2 2/15.
2. 9 1/7 - (3 4/7 + 2 6/7) = 7 4/7.
3. (7 - 3 3/10) + 2 9/10 = 9 9/10.
