Question

express 0.235 bar in the form of p/q form , where p nd q are integers nd q≠0.

Answer 1

Let x= 0.235 bar ----1
1000x = 235.235 bar------2
Subtract 1 from 2
1000x-x = 235.235 bar - 0.235 bar
999x = 235
x = 235/999
Therefore, 0.235 bar = 235/999

Answer 2

$\underline{\bold{Answer :}}$

Answer is 233 / 990

Solution :

$\sf 0.2 \overline{35}$

Let x = $\sf 0.2 \overline{35}$

⇒ x = 0. 23 53 53 535........( i )

Multiply both sides by 10,

⇒ 10x = 2. 35 35 35 35...... ( ii )

Multiply both sides by 100,

⇒ 1000 x = 235. 35 35 35...... ( iii )

On subtracting ( ii ) from ( iii )

1000 x - 10 x = 235 - 2

⇒ 990 x = 233

⇒ x = $\sf \frac{233} {990}$

Therefore, $\sf 0.2 \overline{35} = \frac{233} {990}$
