Question

Express the 0.5 bar in the form of P and Q ​

Answer 1

Step-by-step explanation:

Let x = 0.5 bar

As there is one number under bar, multiply by 10 on both sides,

10 × x = 10 × 0.5 bar

10x = 5.5 bar

Subtract x from both sides

10x = 5.5 bar

- x = -0.5 bar

_____________

9x = 5 [bar cancelled]

_____________

x =5/9

NOW,

0.5 bar in p/q form is 5/9

i hope this will help you

Answer 2

Step-by-step explanation:

Hello mate

Here is your answer

Let x = 0.5..... (i)

On multiplying both sides by 10 (periodicity =1)

we get,

10x = 5.5555...... (ii)

(ii) -(i)

=> 10x -x = 5.5......-0.5555

=> 9x = 5

=> x = 5/9

So, 0.5......= 5/9
