To find out the total time Jake and Kyile spent working in their project we have to make a multiplication of the time spent and the days they did it: jake = (3/4)*2 = 6/4 = 3/2 so Jake spent 3/2 hours working in his project, that is 1.5 hours
I think this because half of 40 is 20 so that's 50 percent then 4 is 10 percent times that by 2 its 70 percent I think bit dont trust me I'm just doing this in my head..
