# The value of 1.999... in the form p/q, where p and q are integers and q ≠ 0 , is

a. 19/10

b. 1999/1000

c. 2

d. 1/9

**Solution:**

Let us simplify each option

a. 19/10 = 1.9

b. 1999/1000 = 1.999

c. 2

d. 1/9 = 0.111….

Consider x = 1.999 …. (1)

Let us multiply equation (1) with 10

10x = 19.99 …. (2)

__Subtracting__ equation (1) from (2)

9x = 18

Dividing both sides by 9

x = 2

Therefore, the value of 1.999... is 2.
