B, C, and D
Hope this helped:)
Can you show the full picture
bearing in mind that 1Kg ≈ 2.2lbs.
so, if a baby is say 2.2lbs, and then it doubles in weight, to 4.4lbs.
well, we know when the baby was 2.2lbs it was exactly 1Kg, but when it went up to 4.4lbs, is it 2Kgs? well, yes, 2Kgs = 2.2 + 2.2 or 2(2.2).
so, multiplying the lbs value by some factor, will retain the Kg:lbs ratio.
A is not part of the problem, and it's what makes the condition false. B is the opposite of the statement being proved. C is the condition, not the hypothesis. However, D is the statement we are trying to prove, or the hypothesis.
The answer is 6.75 or 6 75/100 but you need to simplify.
