In Excel, if you divide 2 by 8, the result is 0.25. if you format the cell as a fraction, the cell might show 1/4 as the result.
What if you want to show the result as a ratio? How can you get the cell to show 1:4 instead of 1/4? There may be other ways, but here's the formula that I used.
=B2/GCD(B2,C2) & ":" & C2/GCD(B2,C2)
This formula requires that the Analysis ToolPak be installed, in Excel 2003 and earlier versions. It divides each cell by the greatest common divisor (GCD), and puts a colon between the two numbers. Would you use a different formula? __________________
