Answer 1

Resposta:

Explicação:

1)-Complete

a)-

*0,5h___s*

( 1 hora = 60 min) e (1 min = 60 s) ENTÃO 1hora = 60x60 =3600s)

0,5h = 0,5(3600)

0,5h = 1.800s

b)- *2h____s*

2h = 2(3600)

2h = 7.200s

c)- *3,5h____min*     ( 1 hora = 60 min)

3,5h = 3,5(60)

3,5h = 210 min

d)- *3m____cm*   ( 1m = 10dm)e (1m = 10x10 = 100cm)

3m = 3(100)

3m = 300cm

e)- *2,5m____cm*

2,5m = 2,5(100)

2,5m  =250m

f)- *0,5m____cm*

0,5m = 0,5(100)

0,5m  = 50cm

g)- *20cm____m*     INVERSO

20cm = 20: 100

20cm =  0,2m

h)- *5kg____g*     ( 1kg = 1000g)

5kg = 5(1000)

5kg = 5.000g

i)- *1,5g_____kg* INVERSO

1,5g = 1,5 : 1000

1,5g = 0,0015 kg

j)- *2t____kg*    ( 1t = 1000kg)

2t = 2(1000)

2t = 2.000 kg

K)- *300kg____t*   INVERSO

300kg = 300 : 1000

300 kg = 0,3t

l)- *1000g____kg*   INVERSO

1000g = 1000 : 1000

1000g = 1 kg
