Question

5/7-2/7 +2 +4/7 -2 2/5 -1/5 ___ =??

Answer 1

$\tt\displaystyle \frac{5}{7} - \frac{2}{7} = \frac{3}{7} \\\\ \frac{3}{7} + 2 = 2 \frac{3}{7} \\\\ 2 \frac{3}{7} + \frac{4}{7} = 2 \frac{7}{7} = 3 \\\\ 3 - 2 \frac{2}{5} = 2 \frac{5}{5} - 2 \frac{2}{5} = \frac{3}{5} \\\\ \frac{3}{5} - \frac{1}{5} = \frac{2}{5}$

Answer 2

Let's break this down step by step:

1. Subtract 2/7 from 5/7: (5/7) - (2/7) = 3/7

2. Add 2 to 3/7: 2 + 3/7 = 14/7 + 3/7 = 17/7

3. Add 4/7 to 17/7: (17/7) + (4/7) = 21/7

4. Subtract 2 from 21/7: (21/7) - 2 = (21/7) - (14/7) = 7/7 = 1

5. Subtract 1/5 from 2 2/5: (2 2/5) - (1/5) = (12/5) - (1/5) = 11/5

So, the answer is 11/5.
