Sean read 1/5 of a book in 1,1/2 hours. how long will it take for sean to 1/2 of the book? i will mark

Your answer would be 3 hours and 45 mins. multiply it by 2 and there is 3 hours. then he has to read 2\5 of the book then now you have to add. 1\5 by two and that's the answer 3 hours 45 min

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
