Question

It is 42 1/2 miles from Eaton to Baxter and 37 4/5 miles from Baxter to Wellington. How far is it from Eaton to Wellington if you go by way of Baxter?

Answer 1

All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...

42 + 37 = 79 

Now we need to add the fractions 

$\frac{1}{2} + \frac{4}{5} = ...$

To add we need a common denominator. 
2 and 5 can both go into 10, so that will be a our common denominator. 
Now you have... 
$\frac{5}{10} + \frac{8}{10} = \frac{14}{10}$
which is equal to $1 \frac{2}{5}$
add that to the 79 we got earlier ...

The toal and final answer is $80 \frac{2}{5}$ miles !
