Answer 2

I can help you with math problems. Here is the detailed solution for your question:

$$ \begin{align*} 2 \frac{1}{15} : \left(\frac{8}{25} + \frac{9}{20}\right) - 1 \frac{29}{35} \times \frac{5}{4} &= \frac{31}{15} : \left(\frac{32}{100} + \frac{45}{100}\right) - \frac{64}{35} \times \frac{5}{4} \\ &= \frac{31}{15} : \frac{77}{100} - \frac{320}{140} \\ &= \frac{31}{15} \times \frac{100}{77} - \frac{80}{35} \\ &= \frac{3100}{1155} - \frac{80}{35} \\ &= \frac{3100 \times 35 - 80 \times 1155}{1155 \times 35} \\ &= \frac{108500 - 92400}{40325} \\ &= \frac{16100}{40325} \\ &= 0.399 \overline{012345679} \end{align*} $$

The answer is approximately 0.399. The exact answer is a repeating decimal with the digits 012345679 after the decimal point.Ответь+подробно.+2+1/15+:+(+8/25+++9/20)+-+1+29/35+*+5/4+=
