Answer 1

А) 5 3/11+2 4/11- 3 8/11=
58/11+26/11-41/11=
58+26=84
84-41=43
Ответ 43/11 или 3 10/11

Б) 4 5/13+ 2 4/13- 1 10/13=
57/13+30/13-23/13=
57+30=87
87-23=64
Ответ: 64/13 или 4 12/13

Answer 2

1)7 7/11
2)занимаем из целой части
Получается :6 18/11-3 8/11=3 10/11
Следущий пример :
1)6 9/13
2)занимаем из целой части
Получается :5 22/13-1 10/13=4 12/13
Надеюсь правильно)

Answer 3

To add or subtract mixed fractions, you need to follow a few steps. First, convert the mixed fractions into improper fractions. Then perform the addition or subtraction operation, and finally, simplify the result back to a mixed fraction if needed.

Let's start with the addition:

1. Convert the mixed fractions to improper fractions: 5 3/11 = (5 * 11 + 3) / 11 = 58/11 2 4/11 = (2 * 11 + 4) / 11 = 26/11 3 8/11 = (3 * 11 + 8) / 11 = 41/11

2. Perform the addition: 58/11 + 26/11 - 41/11 = (58 + 26 - 41) / 11 = 43/11

3. Simplify the result: The fraction 43/11 can be written as a mixed fraction: 43/11 = 3 10/11

Now, let's move on to the subtraction:

1. Convert the mixed fractions to improper fractions: 4 5/13 = (4 * 13 + 5) / 13 = 57/13 2 4/13 = (2 * 13 + 4) / 13 = 30/13 1 10/13 = (1 * 13 + 10) / 13 = 23/13

2. Perform the subtraction: 57/13 + 30/13 - 23/13 = (57 + 30 - 23) / 13 = 64/13

3. Simplify the result: The fraction 64/13 can be written as a mixed fraction: 64/13 = 4 12/13

So, the final results are:

1. 5 3/11 + 2 4/11 - 3 8/11 = 3 10/11
2. 4 5/13 + 2 4/13 - 1 10/13 = 4 12/13
