Simplifying the Product: (1 - 2/5) x (1 - 2/7) x (1 - 2/9)
This problem involves a series of multiplications with fractions. Let's break it down step by step to find the solution.
Simplifying Each Term
-
(1 - 2/5): To subtract fractions, they need a common denominator.
- 1 can be written as 5/5.
- (5/5 - 2/5) = 3/5
-
(1 - 2/7):
- 1 can be written as 7/7.
- (7/7 - 2/7) = 5/7
-
(1 - 2/9):
- 1 can be written as 9/9.
- (9/9 - 2/9) = 7/9
Multiplying the Simplified Terms
Now we have: (3/5) x (5/7) x (7/9)
When multiplying fractions, we multiply the numerators and the denominators:
- (3 x 5 x 7) / (5 x 7 x 9)
We can cancel out the common factors of 5 and 7:
- 3/9
Simplifying the Final Result
The final result, 3/9, can be simplified by dividing both numerator and denominator by 3:
- 1/3
Therefore, (1 - 2/5) x (1 - 2/7) x (1 - 2/9) simplifies to 1/3.
