For your example think about how 6/9 * 9/144 = 9/9 * 6/144

2018-01-30 04:51:42 UTC  

The 9/9 is 1 and can therefore be ignored

2018-01-30 04:51:50 UTC  

If you are trying to reduce a fraction start with a common number and just work down.

So like with 54/1296, both are multiples or 9. I knew 54 was and I checked 1296. That's 6/144. I see if 6 can be used to divide 144, and since it can it becomes 1/24.

2018-01-30 04:52:46 UTC  

6/144 = 6 /(24 * 6) = 6/6 * 1/24

2018-01-30 04:53:01 UTC  

If you are unsure there to start diving top and bottom by 2 works if both numbers are even.

2018-01-30 04:53:17 UTC  

^ this

2018-01-30 04:57:50 UTC  

This is so complicated lol. Okay. So just find the GCD and then reduce it down.

2018-01-30 04:58:18 UTC  

Or in this case, I could just divide 6/144

2018-01-30 04:58:25 UTC  

Right?

2018-01-30 04:58:29 UTC  

Yes

2018-01-30 04:58:56 UTC  

Because the 9s happen to cancel out

2018-01-30 04:59:06 UTC  

And if it's not a problem where it can cancel out then what?

2018-01-30 05:00:10 UTC  

You can find the GCD

2018-01-30 05:01:22 UTC  

Okay

2018-01-30 05:02:17 UTC  

Thanks. Yall

On another note, why do we teach PEMDAS when it should be PEDMSA?

2018-01-30 05:05:21 UTC  

Multiplication and division are the same really

2018-01-30 05:05:35 UTC  

Same with addition and subtraction

2018-01-30 05:05:50 UTC  

So PEMDAS is easier to remember

2018-01-30 05:05:54 UTC  

I've gotten answers wrong for doing multiplication first sometimes though

2018-01-30 05:06:06 UTC  

And same with addition and sibtraction

2018-01-30 05:07:46 UTC  

You might be breaking another rule or your teachers suck. Unless I’m forgetting something that’s wrong and you shouldn’t have been marked down

2018-01-30 05:09:13 UTC  

If you are using a computer program it is probably programmed by someone diverse and doesn’t account for multiple but equally valid ways to the answer

2018-01-30 05:09:25 UTC  

This class is online. The teacher just supervises. I followed PEMDAS as taught but when I did I kept getting answers wrong and when I viewed the solution they were doing division first

2018-01-30 05:09:28 UTC  

Yes omg

2018-01-30 05:09:54 UTC  

The worst part is that it only counts one answer correct. And if you don't get that correct it marks it wrong even if you understand the concept

2018-01-30 05:10:00 UTC  

Bring it up in office hours, that’s BS

2018-01-30 05:10:11 UTC  

And you cant practice the same problem twice

2018-01-30 05:10:19 UTC  

It keeps changing it up

2018-01-30 05:10:25 UTC  

This sounds a lot like mastering physics

2018-01-30 05:10:27 UTC  

Whenever you get it wrong

2018-01-30 05:10:40 UTC  

Yeah haha and I am not a scientific person

2018-01-30 05:10:47 UTC  

I'm majoring in media production.

2018-01-30 05:12:20 UTC  

Bring it up with whoever you can. If you actually understand the concepts you shouldn’t be graded down

2018-01-30 05:14:51 UTC  

I might. My instructor is Asian with a broken accent of course. Yeah I've demonstrated that I understand how to do the concepts

2018-01-30 05:16:07 UTC  

Send screenshots or show photos of your work and really nail them down. Say “show me what’s wrong or the programming is bad”

2018-01-30 05:16:46 UTC  

If you have white TAs or even TAs that speak English use them

2018-01-30 05:16:56 UTC  

What's a TA?

2018-01-30 05:17:01 UTC  

Oh nvm

2018-01-30 05:17:02 UTC  

LOL
