A another conversion problem.
00:02
And in these conversion problems, you can do them often in just one long equation.
00:07
And i tend to break them up because it makes it easier to see what the different parts are.
00:12
And i will do that here as well.
00:14
So the first thing we are given is that we have a child who's 36 pounds.
00:21
And all the other units, of course, are in metric.
00:25
And so we need to convert 36 pounds into kilograms.
00:29
And remember that one kilogram is 2 .205 pounds.
00:39
And of course, this pounds is in the numerator.
00:43
We can imagine it looks like that.
00:45
And so we have to cross that one out with that one by putting this one in the denominator.
00:49
All right.
00:50
And so when we do the math, we end up with a child who weighs about 16 kilograms.
00:57
Keep in mind, that's two significant digits.
00:59
So that's going to be two significant digits...
