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.
