Question

Thomas Cann lived 1/5 of his life in Atlanta, Georgia, 1/4 of his life in Rome, Italy, 1/3 of his life in Los Angeles, California, and the rest of his life in Miami, Florida. How many years did he live in Miami if he died at the age of 60?

Answer 1

60(1- 1/5 - 1/3 - 1/4) = 60(60/60 - 12/60 - 20/60 - 15/60) = 60(60-12-20-15)/60= 60 -47 = 13

years = # of years Tom lived in Miami
