Macy 5 miles because she ran 4 times more than Jackson in relation to Jackson ran 5 mile, this problem can oftenly be seen as
[tex]j = 20 \div 4[/tex]
which would end up in the answer being 5 which is the right answer while someone else can see it as
[tex]j = 20 - 4[/tex]
which would equal 16 which is incorrect because the problem didn't say that Jackson ran one mile nor 4 miles which would be 4*4 or 16 when the correct answer is 20/4=5 because 4*5=20
