The width of a standard newspaper column is 2.625 in., and the length of a standard
column is 19.5 in. Express the ratio of the two measurements as a ratio of whole
numbers.

Multiply both by the same number, and the ratio will remain the same.
2.625 x 1000 = 2,625
19.5 x 1000 = 19,500
If you want you can now divide each number by 375 to get the smallest possible whole numbers that still have the same ratio
2,625 / 375 = 7
19,500 / 375 = 52
So the ratio "2.625 to 19.5" is the same as "7 to 52", or conversely, "19.5 to 2.625" is the same at "52 to 7".

How to Determine a Ratio
Ratios represent how one quantity is related to another quantity.
A ratio may be written as A:B or A/B or by the phrase "A to B".
A ratio of 1:5 says that the second quantity is five times as large as the first.
The following steps will allow a ratio to be determination if two numbers are known.
Example: Determine the ratio of 24 to 40.
Divide both terms of the ratio by the greatest common factor (24/8 = 3, 40/8=5)
State the ratio. (The ratio of 24 to 40 is 3:5)

19.5 = 39/2
2.625 = 2 5/8 = 21/8
So 39/2 * 8/21 = 156 / 21 = 52/7

Remove the decimals by multiplying:
l/w = 19500/2625. Now reduce these by dividing by 125:
156/21. Now divide each by 3: 52/7
