Answers in simplest form.

So, 36 over 5, i need to change that so that it has a denominator of 10.
00:11
So 5 times 2 is 10, so 36 times 2 is 72.
00:22
So 72 minus 33 is 39 over 10, which is 3 and 9 tenths.
00:35
I need to change one half to five tenths and four -fifths to have to have ten as the denominator, so eight -tenths.
00:47
So i have seven and thirteen tenths, which is equivalent to eight and three -tenths.
00:57
So then i have five and one -fourth and two and four -fifths.
01:06
So five is going to go here for sixteen here.
01:12
So 21 over 20.
01:14
So that would be 8 and 1 .20th.
01:21
So then for this next one, i have to have 15 as my common denominator.
01:25
So 12 fifths becomes 36 .15th and i'm subtracting 1615th, which is 2015th, which is 1 in 515th, which is 1 and 1 3rd.
01:43
So the next one, i have 3 minus 5 plus 1 because keep change change.
01:59
So that's negative 1 over 2.
02:03
For this next one, i have 4 in 2 7ths minus 3 in 1 half, which is 1114th.

I'm going to use a calculator right now because, but if you need a certain one that you need to show work for, i just suggest that you send a photo of the one that you need work shown for, and then that specific one can.

But it's just difficult to stick to the timeline when we have a whole worksheet to do.
02:41
So 9 tenths times negative 4 fifths is negative 36 over 50.
02:48
And negative 36 over 50 becomes negative 18 over 25.
02:56
So 3 and 6th.
03:00
Times 2 and 2 5ths, which is 9 .35th.
03:10
So negative 1925th, i'm sorry, 19 .5th, divided by 1310.
03:19
Remember, if you need to show work for this, you do keep, change, flip.
03:28
And so that's one, two...
