i need help with decimals and ratios

Question

The "golden ratio" has been used since the ancient Greeks to give objects (like the Parthenon) pleasing proportions. Its value is about 1.62:1. If you want to make a table top to those proportions, and it is to be 38 inches wide, how long should it be?

Answer 1

The width is 38 inches, and the ratio which we want is 1 : 1.62

Hence, the length of the table will be
= 38 * 1.62
= 61.56 inches
