Решение:
- \( (143.65 - 40.7) : 2.9 - 17.75 \)
\( 102.95 : 2.9 - 17.75 \)
\( 35.5 - 17.75 = 17.75 \) - \( 8.74 : (2.43 + 2.17) - 0.475 \)
\( 8.74 : 4.6 - 0.475 \)
\( 1.9 - 0.475 = 1.425 \) - \( (21.2544 : 0.9 + 1.02 \cdot 3.2) : 5.6 \)
\( (23.616 + 3.264) : 5.6 \)
\( 26.88 : 5.6 = 4.8 \)
Ответ: 17.75; 1.425; 4.8.
