Question

Edgar ran 18 2/5 miles and walked 10 1/2 miles. How much further did Edgar run than walk?

Answer 1

`7(9)/(10)`

Explanation:

Find the greatest common denominator. It's 10 in this case.

`18(2)/(5)-10(1)/(2)=18(4)/(10)-10(5)/(10)=7(9)/(10)`

Answer 2

7 9/10

Explanation:

18 2/5 - 10 1/2 = 7.9/10
