Ответ:
- \(12.7\cdot0.5-9.4\cdot0.8=6.35-7.52=-1.17\).
- \((42-17.36)\cdot0.06=24.64\cdot0.06=1.4784\).
- \((0.22+4.3)(7.225-3.6)=4.52\cdot3.625=16.385\).
- \((10.84-9.6)\cdot0.65-7.2+25.58=1.24\cdot0.65+18.38=19.186\).
- \(16.7-4(0.006+0.994)(4\cdot0.8-2)=16.7-4\cdot1\cdot1.2=11.9\).
Ответ: 1) −1,17; 2) 1,4784; 3) 16,385; 4) 19,186; 5) 11,9.
