Question

Calcule:

1/3 de 1/2 hora:
1/4 de 3/5 do metro:
2/3 de 3/5 do litro:

Answer 1

-> 1/3 de 1/2x 60 min

-> 1/3 de 30 min

-> 30/3 = 10 min

--------

-> 1/4 de 3/5 de 1 metro (m)

-> 1/4 de 3/5 de 100 centímetros (cm)

-> 1/4 de (3x100)/5

-> 1/4 de 60

= 1 x 60/4

= 15 cm

-------------------------------------------

-> 2/3 de 3/5 do litro (L)

-> 2/3 de 3/5 de 1000 mililitro (mL)

-> 2/3 de (3 x 1000)/5

-> 2/3 de 600

-> (2 x 600)/3

= 400mL
