Question

Last year Eric went on 6 business trips. The number of days of each was 5, 2, 8, 12, 6, and 3. How many weeks did Eric spend on business trips last year

Answer 1

i would say 5 weeks and 1 day but im not entirely sure. i just moved the numbers around. so 5 plus 2 equals 7 days which is one week. if you take 1 away from 8 it gives you 7 day, 2 weeks now. then i added that one day to the 6 to make 7 days, now 3 weeks. took away 5 from 12 to give me 7 days, 4 weeks now. then added that 5 to the 3 to make 8 days, 5 weeks and 1 day. i might have over complicated the problem but that is how i attacked it. hope it helps
