Question

Erin walked 1 mile from her house to the Library. Along the way, she passed several places shown on the number line below. Which place is 4/8 mile from Erin's house?

A. The fire station
B. The park
C. The School
D. The market

Answer 1

The school is halfway between, or 4/8. I recommend counting the lines on the paper and seeing which one is halfway through. 

Answer 2

There are 8 divisions of the line between 0 and 1 mile.  The school is 4 divisions along the way.  Note:  4/8 mile = 1/2 mile.
