And so questions asking us which of the distances in the pairs is the shorter distance.
00:17
So, for example, we have 20 millimeters versus 0 .3 meters.
00:29
And so which of those are shorter? well, different ways to do it, but what's a third of a meter? well, a meter, remember, is 1 ,000 millimeters.
00:41
It's 100 centimeters.
00:43
So a third of a meter would be approximately 33 millimeters.
00:50
And so obviously, 20 millimeters would be the correct answer.
00:54
That's much shorter than 33 millimeters.
00:58
Millimeters.
00:59
For the second one, we're asked to compare one inch versus 30 millimeters.
01:08
And again, we're sort of asked to make a judgment on reasonableness, not to do a detailed calculation, but just kind of like, which of these is probably shorter...
