Answer 1

Alecia lives farther from school

Explanation:

Georgia

we know that

The distance from the school to her home is 67/100 of a mile

`(67)/(100)=0.67\ miles`

Alecia

we know that

The distance from the school to her home is

3/10 of a mile plus 4/10 of a mile

so

`(3)/(10)+(4)/(10)=(7)/(10)=0.7\ miles`

Compare the distances

`0.7\ miles>0.67\ miles`

therefore

Alecia lives farther from school
