No. supposed to solve it

PEMDAS

I meant I knew the answer

Order of operations

Yep did that

Would a photo help for reference?

Yes

Yes.

How do I get 1/24?

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

Simplify 6/9 * 9/144

The 9s cancel out

54/54 = 1 and 1296/54 = 24

And 6 goes into 144 24 times

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

Is that mastering physics but for math

Yes

Or what @micbwilli said

Either works

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

Both rely on what I did above with another example

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

The 9/9 is 1 and can therefore be ignored

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.

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

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

^ this

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

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

Right?

Yes

Because the 9s happen to cancel out

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

You can find the GCD

Okay

Thanks. Yall

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