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

Okay thanks @GetOffMyState#8267

@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

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?

Multiplication and division are the same really

Same with addition and subtraction

So PEMDAS is easier to remember

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

And same with addition and sibtraction
