You can the fractions of the problem with denominators (the bottom numbers). Change the denominators to ten. 1/2 = 5/10 4/5 = 8/10 Then you add those two fractions. 5/10+8/10 = 13/10= 1 3/10 Then you add your two whole numbers 42+37= 79 Then add the fraction and whole number together 79+1 3/10= 80 3/10 miles
