Question

3 3 - минус - = 7 8 1 - + 0.2= 3

Answer 1

$\frac{3}{7}- \frac{3}{8}= \frac{24-21}{56}= \frac{3}{56} \\ \\ \frac{1}{3}-0,2= \frac{1}{3}- \frac{1}{5}= \frac{5-3}{15}= \frac{2}{15}$

Answer 2

It seems like you've provided a series of mathematical operations, but the format is not entirely clear. Let's break down the expression step by step:

1. 3 - 3 = 0
2. 0 - 7 = -7
3. -7 + 8 = 1
4. 1 - 1 = 0
5. 0 + 0.2 = 0.2
6. 0.2 = 3

The expression you provided does not yield the result "3." It appears to result in "0.2." If you have any specific questions or if you meant something different, please clarify, and I'd be happy to help further.
