To find the number that is one fifth of one fourth of one ninth of 900, we will break this down step by step.
First, we need to calculate one ninth of 900:
- One ninth of 900 is 900 ÷ 9 = 100.
Next, we find one fourth of this result:
- One fourth of 100 is 100 ÷ 4 = 25.
Finally, we calculate one fifth of the last result:
- One fifth of 25 is 25 ÷ 5 = 5.
So, the final answer is 5. This means that one fifth of one fourth of one ninth of 900 equals 5.
