molly ran 2/3 of a mile in 8 minutes . if molly runs at that speed , how long will it take her to run one mile

Sagot :

It would take her 12 minutes because if you mutipy 2/3 by 3/2 then you get 1 (as in one mile) and then you have to do that to the other side too so then you multiply 8 by 2/3 and get 12
