Ned walks 6/10 of a mile to school. fred walks 9/15 of a mile to school. who walks farther?

There are a few ways to solve the problem. I will use 2 ways. You can use equivalent fractions.
Way 1:
You find the LCM of 10 and 15.
10: 10,20,30,40,50
15: 15,30,45,60,75
LCM of 10 and 15: 30
30/10=3
6*3=18
6/10=18/30
30/15=2
9*2=18
9/15=18\30
18/30=18/30
Since 6/10=9/15, Ned and Fred walked the same miles to school.
Way 2:
You could simplify 6/10 into 3/5 and simplify 9/15 into 3/5 by using GCF and since 3/5=3/5, 6/10=9/15. Since 6/10=9/15, Ned and Fred walked the same miles to school.

The point that represents what the local business will donate is (10, 5). After testing the point in both equations, you can see that student B wrote the correct equation; 5 = 1/2  (10).
