Final Answer:
Archie sold
cakes.
Step-by-step explanation:
To find the total number of cakes Archie sold, we add the whole number and the fractional part. Archie sold 3 whole cakes and
of another cake. Combining these, we get
cakes in total.
To break it down further, we understand that
of a cake is less than one whole cake. Therefore, when added to the three whole cakes, the total is not four but still less than four. This is evident in the mixed number representation
The fraction
indicates that Archie sold a portion of another cake, which is
of a full cake.
