Sample Response: A model is an estimate or approximation of a data set. In the real world, there are too many variables to know exactly what will happen. However, if a model is a good fit, then it can be used to make predictions about what will happen. With a useful model, a predicted value should be a good estimate of an observed value.

Okay so. 2/5=24/60 (multiply 2/5 by 12) 2/3=40/60 (multiply 2/3 by 20) 1/4=15/60 (multiply 1/4 by 15) Then, Add 24/60 with 40/60 which is 64/60 after you get that you subtract by 15/60 and you get 49/60. Hope this helps!^^
