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. The answer is 7/52 but I cannot for the life of me figure out how.

2.625:19.5
=2625:19500 divide by 25
=105:780 divide by 5
=21:156 divide by 3
=7:52
