a)
20 / (1/5) = 20 * 5 = 100
Ou seja, com 20 litros, encho 100 latas de (1/5) de litro.
b)
(2/5) * (3/100) = 6/500 = 3/250
c)
2*(2/3)/(2/4) = (4/3)/(2/4) = (4/3)*(4/2)
2*(2/3)/(2/4) = 16 / 6 = 8/3
d)
6 / (1/2) = 6 * 2 = 12
e)
(2/6)/1*(2/6) = (2/6)*(2/6) = 4/36 = 1/9
20 / (1/5) = 20 * 5 = 100
Ou seja, com 20 litros, encho 100 latas de (1/5) de litro.
b)
(2/5) * (3/100) = 6/500 = 3/250
c)
2*(2/3)/(2/4) = (4/3)/(2/4) = (4/3)*(4/2)
2*(2/3)/(2/4) = 16 / 6 = 8/3
