$1. \: 45 \div 9 \times 18 \div 35 = 5 \times 15 \div 35 = 75 \div 35 = 2.1 \\ 2. \: 30 \div 6 \times 14 \div 25 = 5 \times 0.56 = 0.28 \\ 3. \: 40 \div 8 \times 36 \div 4 \div 5 = 4 + 136 = 200 \div 4 \div 5 = 50 \div 5 = 10 \\ 4. \: 62 - (17 + 18) = 62 - 35 = 27 \\ 5. \: 100 - (43 + 47) = 100 - 90 = 10 \\$

28+(52-16)= 28+36= 64
