Answer:Portion put up on Wednesday =1/12
Explanation:
Since we are dealing with fraction
Let the total fence = 1 whole
such that fence put up on Monday = 3/4
and fence he put p on Tuesday = 1/6
Since he put up the rest on Wednesday, To find the portion put up we have that
Portion put up on Wednesday =Total portion of fence - ( Portion put up on Monday and Tuesday)
=1- ( 3/4 + 1/6)
= 1- 18+ 4/ 24
=1- 22/24
= 2/24
Portion put up on Wednesday =1/12
