  1. 24,936 : 24 = 1,039, так как 24 × 1,039 = 24,936.

  2. 24,8 × 35 = 24,8 × (30 + 5) = 744 + 124 = 868.

  3. 0,748 × 18 = 0,748 × (20 − 2) = 14,96 − 1,496 = 13,464.

  4. 10 − 0,686 = 10,000 − 0,686 = 9,314.

  5. 110,01 − 98,997 = 110,010 − 98,997 = 11,013.

  6. 409,357 + 28,581 = 437,938.

Ответ: 1,039; 868; 13,464; 9,314; 11,013; 437,938.
