Harry sold 8 smalls cars out of 11 cars.
At the end of the sale He sold 33 cars.
In order to determine how many small cars did Harry sell in the week, you take into account that the proportion of small cars for each sale is 8/11.
To find the total small cars sold in the week you multiply the proportion of small cars by the total cars sold in the week, just as follow:
(8/11)33 = 8(33/11) = 8(3) = 24
Hence, the small cars sold during the week were 24.
