[00:00:00]Think adding and subtracting three fractions is hard? Watch this simple method that makes the whole question easy in seconds.

[00:00:09]So, we draw one line. We find the lowest common denominator.

[00:00:12]And we go to the largest number, which is eight.

[00:00:15]We see if the other numbers go into eight.

[00:00:18]Six doesn't go into eight, so we go to the next multiple, which is 16.

[00:00:23]And again, six doesn't go into 16, so we go to the next multiple of eight, which is 24, and that works.

[00:00:29]Now, 24 divided by four, you get six, so you multiply the top number by six.

[00:00:37]And 24 divided by six is four, so you multiply the five by four.

[00:00:44]And 24 divided by eight is three, so you multiply the seven by three.

[00:00:53]Now, you have 18 plus 20 minus 21, which gives you 17. So, you have 17 over 24 for final answer.
