Yeah that's a good way to check. I try my best lol

2018-01-30 04:34:55 UTC

Anyone @here to help with another math question?

2018-01-30 04:36:05 UTC

I might could. I haven't done math in a bit, but I can do things like the last question posted.

2018-01-30 04:37:15 UTC

I know the answer to this question, I'm just not sure how to solve to get to it

2018-01-30 04:37:44 UTC

6/9 * 3/12 squared - 4/6

2018-01-30 04:38:24 UTC

Is there an equals sign?

2018-01-30 04:39:01 UTC

No. supposed to solve it

2018-01-30 04:39:13 UTC

PEMDAS

2018-01-30 04:39:17 UTC

I meant I knew the answer

2018-01-30 04:39:21 UTC

Order of operations

2018-01-30 04:39:33 UTC

Yep did that

2018-01-30 04:40:11 UTC

Would a photo help for reference?

2018-01-30 04:40:15 UTC

Yes

2018-01-30 04:40:17 UTC

Yes.

2018-01-30 04:41:43 UTC

How do I get 1/24?

2018-01-30 04:42:13 UTC

When I multiply I get 54/1296 and i don't know how to reduce it because I'm bad at fractions

2018-01-30 04:44:07 UTC

Simplify 6/9 * 9/144

2018-01-30 04:44:19 UTC

The 9s cancel out

2018-01-30 04:44:33 UTC

54/54 = 1 and 1296/54 = 24

2018-01-30 04:44:39 UTC

And 6 goes into 144 24 times

2018-01-30 04:45:07 UTC

So cancelled out the 9s and divide 6/144 ?

2018-01-30 04:45:12 UTC

Is that mastering physics but for math

2018-01-30 04:45:16 UTC

Yes

2018-01-30 04:45:36 UTC

Or what @micbwilli said

2018-01-30 04:45:42 UTC

Either works

2018-01-30 04:45:57 UTC

Okay thanks @GetOffMyState#8267

2018-01-30 04:46:32 UTC

@micbwilli could you explain your way a bit more? How do you know that's what your supposed to do?

2018-01-30 04:48:52 UTC

2018-01-30 04:49:16 UTC

Both rely on what I did above with another example

2018-01-30 04:51:18 UTC

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 04:54:57 UTC
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
