Question:
- Expresss 0.9999.... in p/q form.
To find:
- 0.999... in p/q form.
Solution:
Let's take 0.9999.... as x.
Therefore,
x = 0.9999.....(I)
Let's multiply both the sides by 10.
Therefore,
10x = 9.9999...(II)
Now, let's subtract (I) from (II),
Therefore,
Equation(II) - Equation(I)
10x - x = 9.99999.... - 0.9999....
9x = 9
( 0.9999... and 0.9999 got cancelled)
x = 9/9
x = 1
Answer:
Therefore, 0.999.... in p/q form is 1
