It seems like your input includes a mathematical expression followed by some symbols. The expression "0,4×1 7/8" appears to be a combination of multiplication and fractions. Let's break it down:

1. "0,4" likely represents the decimal number 0.4.
2. "×" is the multiplication symbol.
3. "1 7/8" is a mixed number, where 1 is the whole part and 7/8 is the fractional part.

To calculate the result, you would perform the multiplication of 0.4 and 1 7/8:

0.4 × 1 7/8 = 0.4 × (1 + 7/8) = 0.4 × (15/8) = 6/8 = 3/4

So, the result of the expression "0,4×1 7/8" is 3/4. The symbols "пжжжжжжжжжжжжж" don't seem to have a clear meaning in this context. If you meant something different, please provide additional information or clarify your input.
