What I would do is find a similar denominator for 3/5 and 2/3 (15). Next, I would multiply 5x3 =15 and 3x5= 15. If you do something to the bottom then, you need to do it to the top. 3x3= 9 2x5= 10 Finally you subtract each other but, if the second number is higher than the first and the first has a whole, you add the whole. 2 24/15- 10/15= 2 14/15 So, Austin is 2 and 14/15 miles away from his house.
