Решение:
- \( 15,832 \times 1,8 = 28,4976 \)
- \( 24,16 : 5,9 \approx 4,0949 \)
- \( 7,4 \times 500 = 3700 \)
- \( 15,832 + 642 = 657,832 \)
- \( 1,8 \times 9,42 = 16,956 \)
- \( 642 : 9,42 \approx 68,1528 \)
- \( 15,832 + 87,99 = 103,822 \)
- \( 1,8 \times 1,455 = 2,619 \)
- \( 642 : 9,42 \approx 68,1528 \)
