(04.04)marcus painted one-third of his bedroom in fourth-fifths of an hour. at this rate, how long would it take him to paint the entire room? five-twelfths of an hour twelve-fifths of an hour fifteen-fourths of an hour four-fifteenths of an hour

Answer 1

The answere would be twelve fifths of an hour. 12/5 of an hour

Answer 2

Answer:

The answer is 12/5 hours

Step-by-step explanation:

As Marcus paints at the same rate so the time to paint the whole bedroom can be estimated dividing the whole bedroom (1) by this rate. The rate of painting can be calculated as:

R= (1/3 bedroom portion) / (4/5 hour) = 5/12 of bedroom per hour

Then the time will be:

T = 1/R = 1/ (12/5) = 12/5 hours
