Answer:
24
Explanation:
Clara builds 3 parts of the fence per hour--
if she works for 8 hours-- we know she built 3 fences each hour-- you would multiply,
8(hours) x 3 (fences) = 24
we know this is right because 3 parts are built for every hour
(3+3+3+3+3+3+3+3 = 24)
she worked for 8 hours and built 3 parts of the fence every hour
in total, she built 24 parts of the fence.
