Marcus painted of his bedroom in of an hour. at this rate, how long would it take him the paint the entire room?

5/12 of an hour

12/5 of an hour

15/4 of an hour

4/15 of an hour

Step-by-stSo it took him 4/5 of an  hour to paint 1/3  

that means there is still 2/3 to go  

so that means that he will have two times that time to paint the rest of the room

4/5    =  ?  

1/3       2/3  

using cross multiplication

(4/5)(2/3) = (1/3) (?)

8/15 = 1/3 ?

divide both sides by 1/3

so that will be 8/5

that means it will take 8/5 of an hour to complete the rest  

or 12/5 total to do entire room

Hope this helps ;)ep explanation:

the probability is 0
