answers:
nbsale say: Both are even. Divide both by 2, or any larger power of 2, and keep doing that until one of the numbers is odd. (And again and again.) Then see if there are any more common factors.
All you are doing is reducing 256/192 to lowest terms.
-
say: 2.56 /1.92 = 4/3
-
Paul say: So you're starting with 256:192
Look for common factors:
256 = 2^8
192 = 2^6 * 3
divide both by 2^6
2^(8-6) : 3
=2^2 : 3
=4:3

az_lender say: Divide them both by 64 cents, obtaining 4/3.
-
? say: 256/192 = (16×16)/(16×12)
= 16/12 = (4×4)/(4×3) = 4/3

Krishnamurthy say: 4 : 3
