Hi there.
00:03
The question is asking how we should treat units in calculations.
00:09
In any calculations, units should be treated just like variables in algebra.
00:23
In other words, if we see the same unit in the numerator and the denominator, we can cancel it.
00:31
If they are different units, we cannot cancel, and the units would carry along to the answer.
00:36
So just a quick example.
00:38
Let's say i have 3 .6.
00:40
Seven inches and i am trying to convert this to centimeters i know that there are two point i'm sorry me fix that there are 2 .54 centimeters in every inch so i'm using this equality as a conversion factor to get my answer so i see i i see that i have some units here i have inches and you don't need to worry about plural and singular.

They're going to be treated like the same unit.
01:21
Plural will not affect anything.
01:24
All right...
