All right math geeks Ah fine students studying math here
- 00:07
for the aspire thing Which of the following lists of
- 00:11
numbers has ordered from least on the left to greatest
- 00:16
on the right Yikes This does not look pleasant Instead
- 00:23
of throwing our hands in the air in running round

- 00:25
in circles we're going to go through choices just one
- 00:27
by one Well let's see Number line time Negative Five
- 00:30
elevenses close to a half But negative six sevenths is
- 00:35
closer to negative one So this means that negative five
- 00:38
eleven is larger or less negative than negative six seven
- 00:43
so well in cross out a and then similarly negative
- 00:47
point Oh oh three three three It's closer to zero
- 00:50
then his negative point Oh three three five So negative
- 00:54
point o three degrees larger than that So be it
- 00:58
Can't be the right answer either so it was over
- 01:01
quickly So get rid of b next up See One
- 01:04
point one two oh three Four is larger than both
- 01:07
one point one o two three four and one point
- 01:10
one two three four So oh all right b c
- 01:13
While this easier to see if we round off the
- 01:15
last three decimals and one point one two is greater
- 01:18
than both one point one in one point oh oneself
- 01:22
that goes into the discard pile are we've gotten rid
- 01:24
of a b and c here really quickly All right
- 01:26
how about d We've got two twenty thirds than three
- 01:29
eighteenth than for thirteenth While these look kind of correct
- 01:34
the value of a fraction becomes greater as the numerator
- 01:37
increases in the denominator decreases so well let's see Let's
- 01:42
think about this He's probably the right answer but let's
- 01:44
check e So let's see what we have here One
- 01:47
fifth is point two and let's see while they both
- 01:51
equal to tense So the first two numbers are greater
- 01:54
than the last one So it can't be e just
- 01:57
got to be de here and well you really didn't
- 01:59
have do a huge amount of denominator Getting all these
- 02:03
equal the same number would be well into the thousands
- 02:05
and take you a long time on an exam like
- 02:07
this Easier to just eliminate the wrong ones and then
- 02:10
close your eyes and checked deep because that's it That's 00:02:13.56 --> [endTime] the right answer Well done
