Lucas skates 2/8 mile from his home to school. isabella skates 2/4 mile to get to school. who skates farther

Isabella skates further

Isabella skates further.
to answer this, u would have to get a common denominator between the two denominators, 4 and 8 which is 8.
2    4
_ = _
4    8
4/8 is isabella's and 2/8 is Lucas's.
so, isabella skates further.
another way to answer the problem is when the numerator is the same and the denominators are different numbers, the denominator with a smaller number is the greater one.
ex: 1       1
      _ or _
      2      3
1/2 is greater because when u look at a model,  1/2 is greater than 1/3.
anyways, back to the problem, 
2     2
_ or _ 
4      8
2/4 is greater.
