Easy math question.

For what ever reason, I can't remember how to do this, and it's been a while since I have done it...

1/y = 1/48.1 + 1/14.8

I need to find y... I can add fractions, but for what ever reason, I'm not sure how you get it down to a 1/y type value.

1. take the common denominator at the right side --> now you have one fraction on each side.
2. cross multiply
3. solve for y

 

[daveshel]

Start by converting the fractions to the lowest common denominator, then perform the operations on the operands.

 

[dlock13]

1/(1/48.1 + 1/14.8) = y


Multiply each side by Y, then divide to get Y by itself.

Ah, thanks, I knew it was something easy... for what ever reason I was blanking.

just take the whole thing raised to the -1?
