(100-97)*9= 3*(50-47)= 40-3*4= (98-92)*3= 16:2+52= 90-14:2=

Решение:

1. \( (100 - 97) · 9 = 3 · 9 = 27 \)
2. \( 3 · (50 - 47) = 3 · 3 = 9 \)
3. \( 40 - 3 · 4 = 40 - 12 = 28 \)
4. \( (98 - 92) · 3 = 6 · 3 = 18 \)
5. \( 16 : 2 + 52 = 8 + 52 = 60 \)
6. \( 90 - 14 : 2 = 90 - 7 = 83 \)

Ответ: 27, 9, 28, 18, 60, 83.
