Question

Which measurement is most accurate to describe the weight of a baby

5,000 mg
1,400 g
350 mg
4.5 kg

Answer 1

The right choice is (D) 4.5 kg

Explanation:

If we look at the choices given above

5000 mg = 0.005kg which is not possible for the weight of a baby.

Similarly 1400 kg equals 1.4 kg which also doesn't make sense. In the same way 350 mg is also very less value for the weight of a baby so the only option that is suitable is 4.5kg which is option D

Answer 2

Option 4). 4.5 kg

Explanation:

The given options for the weight of a baby are

1) 5000 mg = 5000/1000 gms = 5 gms = .005 kg

2) 1400 g = 1.5 kg

3) 350 mg = 0.35 gms =
`0.35(10^(-3)) kg`

4) 4.5 kg

Out of these options option 4 is the most suitable weight that describes the weight of a baby.
