Answer 2

Solution:

Given number –

$\tt = 0.2 \bar8$

We have to write the number in the form of p/q.

Let us assume that,

$\tt \mapsto x= 0.2 \bar8$

Multiplying both sides by 10, we get,

$\tt \mapsto 10x= 2. \bar8 - (i)$

Again, multiplying both sides by 10, we get,

$\tt \mapsto 100x= 28. \bar8 - (ii)$

Subtracting (i) from (ii), we get,

$\tt \mapsto 100x - 10x= 28. \bar8 -2. \bar8$

$\tt \mapsto 90x= 26$

$\tt \mapsto x= \dfrac{26}{90}$

On simplifying, we get,

$\tt \mapsto x= \dfrac{13}{45}$

✠ Hence, the p/q form of the number is 13/45.

Answer:

• The number in p/q form is - 13/45.
