A sum to the lowest terms whenever possible.

Okay, so 15 and one half, so i'm going to use four as my common denominator, so two times two is four, so one times two is two, and so two plus three is five over four, so i have 15 and five fourth, which equals 16 and one -fourth.
00:25
Then for this next one, i'm going to use 24 as my common denominator.
00:31
So 8 times 3 is 24, so 4 times 3 is 12.
00:35
6 times 4 is 24, so 1 times 4 is 4.
00:40
So then i have 16 over 24, so 32 and 16 over 24.
00:46
And so then i'm going to simplify 16, 24.
00:51
I'm going to divide both by 4.
00:53
And so i get 4 over 6, and i'm going to simplify that even more, divide both by 2.
01:00
I get two thirds.
01:02
So it's 32 and two thirds.
01:07
So for this next one, i have 10.
01:10
So five times two is 10.
01:11
So two times two is four.
01:14
So then i'm going to have five tenths, 49 and five tenths, which equals 49 in one half.
01:24
For this next one, both six and nine, our division, 18 goes into both of those.
01:32
So that's going to be my common denominator.
01:33
9 times 2 is 18, so 2 times 2 is 4.
01:37
6 times 3 is 18, so 2 times 3 is 6.
01:41
So 6 plus 4 is 10 over 18, and then so i have 71 and 10 over 18, which equals 71, and i'm going to simplify this.
01:51
Both 10 and 18 are divisible by 2, so that equals 5, 9th.
01:56
So 71 and 5 9s.
01:58
For the next 1, 7 plus 2 is 9, so 9 over 11.
02:03
And then 108 plus 45.
02:07
So that is 13.
02:09
Carry the 1 .5.
02:12
153 and 9 .11s.
02:15
For the next one, find the difference of the following fractions.
02:17
Reduce your answer to the lowest terms whenever possible.
02:20
So 12 minus 5 is 7 .19th...
