Answer 1

Explicație pas cu pas:

1) 70/3 - 22/3 = 48/3

2) 2,5 ÷ 5 + 0.5= ( ! facem intai operatia de impartire)

0.5 + 0.5= 1

3) 240 cm = 2400 mm

2,4 m² = 240 dm²= 0,00024 hm²

2,4 m³ = 0.0024 dam³ = 2400000mm³

4) P= 2×( L+ l)

2× (2,5 cm+ 3 cm)

2× 5.5 cm = 11 cm

5) 1, 34= 134/100 = 67/50

1, (34)= 134-1/99 = 133/99

1, 3(4) = 134- 13/ 90 = 121/90
