Alfredo walked 24 miles in the walkathon. His friend Terence walked 1/3 as many miles. How many miles did Terence walk?
I really don't understand this problem could someone help me.

Terence walked 1/3 as many miles as Alfredo so you divide 24 with 3. This equals 8. Therefore, Terence walked 8 miles.

Terence walked 1/3 as far as Alfredo.
(1/3) * (24/1) = 24/3 = 8 miles
Check: Terence walked 8 miles. Alfredo walked 24 miles.
3 times 8 = 24
