Back to Simple Algebra: Solve 76.262 Equation

[simpComp]

Hello,

Okay, after doing perhaps 1 hour of math a year for 20 years, I realize I forgot a lot!

Can someone please tell what I need to do if I want to get rid of the denominator of 900 in the following expression:

76.262 = ((124 + 30b - c)/900) + c

Please see attachment to see exact equation...

I am trying to find a number I can multiply 124 so that the result can be divided by 900... but I can seem to find it?

Thanks

nevermind ... digging up my old algebra notes, I figured that I can multiply every term by 900...

jeeeezzze,,,

The denominators shown in the equation are 1000 and 900. See the "76.262". The common factor is 2³3²5³

In all due respect, where do you see 1000 as a denominator?

To get rid of the 900 we could
simply multiply all terms by 900...no?

(900)76.262 =
((900*124 + 900*30b - 900*c)/900) + 900*c

this works!
thanks

Already explained in my post. It is correct, but unnecessary if you wish to maintain decimalized result.

Now that I look at the equation again, my picking at the decimal part, ".262" with denominator of 1000 plays no part in the solution. Changing the form would not be useful unless a specific application depended on it.
