Does the shortcut for this problem apply to all variations?
I've seen them done before like so:
(5150)(7270) / (5150+7270)
It's giving the correct answer on all but this 08A version.
I'm getting 3014, answer key says 3010?!

It might be 3014, but remember the key is written with 3 significant digits, so 3010 would be an acceptable answer on the test

I think problems like these came up on the general math test in the Skow days... sum the inverses, then take the inverse. Pretty quick. Like transforming to "inverse space"...
