Question

7/9 +2/9 1/7 + 6/7 3/5 - 1/5

Answer 1

$1)\frac{7}{9}+\frac{2}{9}=\frac{7+2}{9}=\frac{9}{9}=1\\2) \frac{1}{7}+\frac{6}{7}=\frac{1+6}{7}=\frac{7}{7}=1\\ 3)\frac{3}{5}-\frac{1}{5}=\frac{3-1}{5}=\frac{2}{5}$

Answer 2

Let's perform these arithmetic operations step by step:

1. Adding 7/9 and 2/9: (7/9) + (2/9) = (7 + 2)/9 = 9/9 = 1

2. Adding 1/7 and 6/7: (1/7) + (6/7) = (1 + 6)/7 = 7/7 = 1

3. Subtracting 1/5 from 3/5: (3/5) - (1/5) = (3 - 1)/5 = 2/5

So, the results of the operations are:

1. 7/9 + 2/9 = 1
2. 1/7 + 6/7 = 1
3. 3/5 - 1/5 = 2/5
