First you subtract 3 years from the sum of Mr. Richards' and Mr. Edwards' age because Ms. Richards is 3 years older than Mr. Richards. Then divide 78 by 3 because 2/3's of the years will go to Mr. Edwards and 1/3 of the years to Mr. Richards since he is double the age of Mr. Richards. So 78:3=26 that gives you 26 and the remaining years are 52. Therefore, Ms. Pacheco is 29, Mr. Richards is 26 and Mr. Edwards is 52
