Answer 1

Given information:
* 1 kitten = 1/4 lb
* 0.45 kg = 1 lb
* 6 kittens = ? kg

If 1 newborn kitten is 1/4 pounds, then 4 newborn kittens would be 1 pound, because 1 kitten * 4 = 1/4 pound *4 --> 4 kittens = 1 pound.

If 4 kittens = 1 pound and 1 pound = 0.45 kg, then 4 kittens = 0.45 kg.

If 4 kittens = 0.45 kg, then 2 kittens = 0.225 kg, because 4 kittens / 2 = 0.45 kg / 2 --> 2 kittens = 0.225 kg.

If 4 kittens = 0.45 kg and 2 kittens = 0.225 kg, then 6 kittens = 4 kittens + 2 kittens = 0.45 kg + 0.225 kg = 0.675 kg.

Answer 2

6 kittens weight 6(1/4) or 3/2 pounds
1 pound/(3/2 pounds) = .45 kg/x kg

2/3 = .45/x
2x = 1.35
x = .675

they weigh .675 kg or 675 g.
