Answer 1

Ответ:

  91; 22; 95; 484; 15; 90

Пошаговое объяснение:

98 - 6 × 4 + 17 = 98 - 24 + 17 = 74 + 17 = 91

54 ÷ 9 × 7 - 20 = 6 × 7 - 20 = 42 - 20 = 22

630 ÷ 7 + 40 ÷ (4 × 2) = 630 ÷ 7 + 40 ÷ 8 = 90 + 40 ÷ 8 = 90 + 5 = 95

420 ÷ 7 × 8 + 24 ÷ 6 = 60 × 8 + 24 ÷ 6 = 480 + 24 ÷ 6 = 480 + 4 = 484

6 × 4 ÷ (560 ÷ 70) × 5 = 6 × 4 ÷ 8 × 5 = 24 ÷ 8 × 5 = 3 × 5 = 15

47 - 30 ÷ 5 + 7 × 7 = 47 - 6 + 7 × 7 = 47 - 6 + 49 = 41 + 49 = 90
