What is one fifth of one fourth of one ninth of 900?

To find the answer, we need to break down the question into smaller steps. Let’s tackle it step by step:

1. Calculate one ninth of 900:

   To find one ninth of 900, we divide 900 by 9:

   900 ÷ 9 = 100

2. Calculate one fourth of the result:

   Now, we take the result from the previous step, which is 100, and find one fourth of it:

   100 ÷ 4 = 25

3. Calculate one fifth of the result:

   Lastly, we take the new result, which is 25, and find one fifth of it:

   25 ÷ 5 = 5

Final Answer: Therefore, one fifth of one fourth of one ninth of 900 is 5.
