I know the answer to this question, I'm just not sure how to solve to get to it
6/9 * 3/12 squared - 4/6
Is there an equals sign?
No. supposed to solve it
I meant I knew the answer
Order of operations
Yep did that
Would a photo help for reference?
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
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
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 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
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
