Давайте сравним выражения: 1. $$586 \times 10.7$$ и $$586 \times 70$$ $$586 \times 10.7 = 6270.2$$ $$586 \times 70 = 41020$$ $$6270.2 < 41020$$, значит $$586 \times 10.7 < 586 \times 70$$ 2. $$36 \times 800$$ и $$36 \times 8 \times 100$$ $$36 \times 800 = 28800$$ $$36 \times 8 \times 100 = 288 \times 100 = 28800$$ $$28800 = 28800$$, значит $$36 \times 800 = 36 \times 8 \times 100$$ 3. $$1200 \div 20$$ и $$1200 \div 100 \div 2$$ $$1200 \div 20 = 60$$ $$1200 \div 100 \div 2 = 12 \div 2 = 6$$ $$60 > 6$$, значит $$1200 \div 20 > 1200 \div 100 \div 2$$ 4. $$900 \div 10 \div 5$$ и $$900 \div 50$$ $$900 \div 10 \div 5 = 90 \div 5 = 18$$ $$900 \div 50 = 18$$ $$18 = 18$$, значит $$900 \div 10 \div 5 = 900 \div 50$$
