If a cake is divided into 10 pieces and Mohiuddin takes 1/3 of the cake, he takes:
(1/3) x 10 = 10/3 pieces
The remaining cake is 10 - 10/3 = 20/3 pieces.
If Morshed takes 1/3 of the remaining cake, he takes:
(1/3) x (20/3) = 20/9 pieces
The number of pieces left is the remaining cake after Morshed has taken his share
which is:
20/3 - 20/9 = 40/9
To express the answer in whole numbers, we need to find a common denominator of 9. Therefore, we have:
40/9 = 4 and 4/9
Therefore, there are approximately 4 pieces left. The answer is "4."
