Пошаговое объяснение:

3/5+2 целых 4/5=2 7/5=3 2/5

8-6 целых 9/10 =2-9/10=1  1/10

Answer 2

$\frac{3}{5} + 2 \frac{4}{5} - 6 \frac{9}{10} = \frac{3}{5} + \frac{14}{5} - 6 \frac{9}{10} = \frac{17}{5} - 6 \frac{9}{10} = \frac{34}{10} - \frac{69}{10} = - \frac{35}{10} = - 3 \frac{5}{10} = - 3 \frac{1}{2}$

Answer 3

To calculate the given expressions, let's break them down step by step:

1. 3/5 + 2 4/5: We can start by adding the fractions first: 3/5 + 2 4/5 = (3 + (2 * 5 + 4)) / 5 = (3 + 14) / 5 = 17/5 So, 3/5 + 2 4/5 is equal to 17/5.

2. 8 - 6 9/10: We need to subtract the mixed numbers: 8 - 6 9/10 = 8 - (6 + 9/10) = 8 - (60/10 + 9/10) = 8 - (69/10) = (80/10 - 69/10) = 11/10 Therefore, 8 - 6 9/10 is equal to 11/10.

In summary:

1. 3/5 + 2 4/5 = 17/5
2. 8 - 6 9/10 = 11/10
