So this question they're asking is to round off the 20 .359 to the nearest tenth.
00:05
So what becomes important here is the nearest tenth would mean that we are looking at just the one decimal place.
00:17
Okay, so we're looking at just the one decimal place.
00:19
So let's concentrate on these three numbers, 3, 5 and 9.
00:27
Now, the rule is, if you have numbers that are greater than 5, okay, so if you have a number that is greater than 5, it would go to the next place.
00:43
So for example, if you have a point 9, okay, so 9 is obviously greater than 5.
00:54
It means that 9 would become a 10.
00:57
Then the 10 would have a decimal obviously shifted towards its left, therefore it will become 1.
01:07
Okay.
01:07
So likewise, if you look at the 9 here, the 9 would obviously become a 10 because it's getting rounded off and the 1 would actually go right here...
