Answer 2

Respuesta:

1) (a+b)×c

(5.4 + 3.2) × 0.61 = 8.6 × 0.61 = 5.246

(2.5 + 2.5) × 1.5 = 5 × 1.5 = 7.5

(6.4 + 5.8) × 7.5 = 12.2 × 7.5 = 91.5

(6.7 + 2.5) × 6.9 = 9.2 × 6.9 = 63.48

2) (a-b)+c

(5.4 - 3.2) + 0.61 = 2.2 + 0.61 = 2.81

(2.5 - 2.5) + 1.5 = 0 + 1.5 = 1.5

(6.4 - 5.8) + 7.5 = 0.6 + 7.5 = 8.1

(6.7 - 2.5) + 6.9 = 4.2 + 6.9 = 11.1

3) a×b-c

5.4 × 3.2 - 0.61 = 17.28 - 0.61 = 16.67

2.5 × 2.5 - 1.5 = 6,25 - 1.5 = 4.75

6.4 × 5.8 - 7.5 = 37.12 - 7.5 = 29.62

6.7 × 2.5 - 6.9 = 16.75 - 6.9 = 9.85
