Question

Latonya is jogging from her house to school. School is 5 1/2 miles from her house. She has gone 1 2/5 miles so far. How many miles does does she still have to jog

Answer 1

Most of the time...actually almost always, it is best to change mixed numbers to improper fractions to do the arithmetic and then change back at the end...so here

 

5 1/2 - 1 2/5 = (11/2) - (7/5) = (55-14)/10 = 41/10 = 4 1/10
