Well, there's your problem, right there.  You didn't show any work of your own.  You ALWAYS get faster service when you show your own work in the VERY FIRST post.

tkhunny · Answer

You can still show your own work.  We'll take anything.

Just build the fraction $\dfrac{500\;stitches}{2/3\;minute}$.  There.  See.  You could have done that.  Can you make the fraction prettier?

twistrose · Answer

but how would you work it

tkhunny · Answer

Simplify the fraction.  $\dfrac{500}{2/3}$.  How do you divide fractions?

twistrose · Answer

you find the reciprocal of the bottom and multiply? right?

tkhunny · Answer

Yup.  Let's see it.

twistrose · Answer

so it'll looklike this:|dw:1455140743215:dw|right

twistrose · Answer

so it'll be 1500/2 which simplifies down to 750/1 which is 750 right?

tkhunny · Answer

Now, go get the units back and you're done.

twistrose · Answer

tkhunny · Answer

Just build the fraction and see where it goes.  IF there is a secret, that's it.
