0.333....
Let x be 0.333.....
and Let 10x be 10 X 0.333...... = 3.33
10 x - x = 3.33 - 0.33
=3
9x = 3
x = 3/9 =1/3!
1/3 is a rational number which is in p/q form where p and q are integers(co primes) and q is not equal to 0.so it can be the answer,if it is right so please give me thumbs up experts

Heya brilliant brainly users........
ur answer are there__________
let x= 0.33333...--------(1)
in equation (1)multiply 10 both side...
10x= 3.3333....------------------------(2)
subtract equation (1)from(2)
10x-x= 3.3333..- 0.3333..
9x= 3
x = 3/9
x=1/3
hopes it will help u
thanks
