Respuesta:

1.= 4

2.= 2.3

3.= 5.18

4.= 38

Answer 2

1) 1.6 + 3 × (5.6 - 4.8) = 1.6 + 3 × 0.8 = 1.6 + 2.4 = 4

2) 4.25 - (1.2 + 0.75) = 4.25 + 1.95 = 2.3

3) 2.48 + 3.1 × 0.4 = 2.48 + 1.24 = 3.72

4) 5 × (3 + 6) - 7 = 5 × 9 - 7 = 45 - 7 = 38

5) 2/4 + (0.5 + 1/5) = 2/4 + (1/2 + 1/5) = 2/4 + 7/10 = 6/5
