This tutorial goes through the answers to question nine in chapter one, section two, practice.
00:06
This question has six part, and it is a test of the fraction operation rules.
00:14
And the actual rules can be found on pages 11, 12, and 16.
00:20
So you want to make sure that you know these because you don't want to make mistakes on your fraction operations.
00:26
So if we have a fraction that is a over a, where the numerator and the denominator, are the same boundaries.
00:32
The answer to that or the simplification of that is one.
00:36
Any number divided by itself is one.
00:39
Now for b, if we have a fraction where it's something over one, so any number over one, any number divided by one is simply that number.
00:48
And remember, the fraction bar represents the division sign.
00:52
So that's really what you're doing here.
00:54
For c, we have an example of, or the rule for multiplying fractions.
01:00
So, when we multiply fractions, we multiply the numerators, and then we write that over the product of the denominators...
