Question

After 8/15 of an hour, Jane has completed painting 3/5 of the wall. At this rate, how much of the wall will she finish painting after 1 hour?

Answer 1

Answer:

Step-by-step explanation:

Find the unit rate for this painting:

 3/5 of wall surface            3/5              15            9

------------------------------- = --------------- * --------- = -----------

         (8/15) hour                 8/15             15             8

Jane could actually paint the whole wall plus 1/8 more of it in one hour.
