Решение:
- 500.1
- \[ (15 \div 1.2) \times (7 \div 1.4) - (1 \div 2.5) \times (3 \div 1.2) \]
- \[ 12.5 \times 5 - 0.4 \times 2.5 \]
- \[ 62.5 - 1 \]
- \[ 61.5 \]
- 500.2
- \[ (1 \div 1.6) \times (26 \div 5.2) + (18 \div 3.6) \times (2 \div 0.25) \]
- \[ 0.625 \times 5 + 5 \times 8 \]
- \[ 3.125 + 40 \]
- \[ 43.125 \]
- 500.3
- \[ 0.063 \div 0.09 + 0.0408 \div 0.017 + 0.00027 \div 0.015 \]
- \[ 0.7 + 2.4 + 0.018 \]
- \[ 3.118 \]
- 301.1
- \[ 28.07 \div 1.4 + 27.75 \div 11.1 - 19.76 \div 15.2 \]
- \[ 20.05 + 2.5 - 1.3 \]
- \[ 22.55 - 1.3 \]
- \[ 21.25 \]
- 301.2
- \[ 17.102 \div 3.4 - 2.472 \div 2.4 + 20.503 \div 2.9 \]
- \[ 5.03 - 1.03 + 7.07 \]
- \[ 4.00 + 7.07 \]
- \[ 11.07 \]
- 301.3
- \[ 0.1 \div 0.002 - (7.91 \div 0.565 - 11.1 \div 1.48) \]
- \[ 50 - (14 - 7.5) \]
- \[ 50 - 6.5 \]
