Answer 1

a) 5cm por 10m= 5cm/1000cm= 1/200

b)2m e 70km= 2m/70000m= 1/35000

c)1800g e 3kg=1800/3000=18/30=3/5

d)40kg e 120kg= 40/120= 1/3

Answer 2

5 cm/10 m  =

1 m = 100 cm  

10 m * 100  = 1000 cm

5cm / 1000 cm =  1/200 cm  ***

b

2 m / 70 km

1 km = 1000 m

70 km * 1000  = 70 000 m

2 m/70 000 m =  1/35 000  m

c

1 800 g/ 3 kg

1 kg = 1000 g

3 kg * 1000  = 3 000 g

1800 g/ 3 000 g =   corta 00   =  18/30 =3/5 ***  por 6

d

40 kg/120 kg  =  por 40   = 1/3 kg ***
