karen is an accountant. she finds she spends two fifths of her work day answering emails. if she spent 3.6 hours answering e mails, how many hours was her work day?
The answer is 8.20 I’m pretty sure because 3.6 is for 2/5 so you would add another 3.6 and you would get 7.12 equals 4/5 and then you would divide 3.6 by 2 and get 1.8 then add 1.8 to 7.12 and get 8.20
