Question

a trip to portland,oragan, from boston will take 7 3/4 hours. assuming we are two thirds of the way there, how much longer, in hours, will the trip take?

Answer 1

it might help to change 7 3/4 to an improper fraction

Answer 2

7 3/4
= 7 + 3/4
= 7/1 + 3/4
= 28/4 + 3/4
= 31/4

Answer 3

now the question says, assuming we are 2/3 of the way , how much time is left for the trip. If you are 2/3 of the way, that leaves you with 1/3 of the way left.
So multiply 1/3 and 31/4
