Question

express 0.8bar in p by q form

Answer 1

Answer:

8/8

Step-by-step explanation:

let x = 0.8

multiple both of sides by 10

x x 10 = 0.8 × 10

10x = 8.8

10x-x 8.8 -0.8

9x=8

x=8 upon 9

ANS 0.8-8upon9

Answer 2

Answer:

0.8(bar) can be written in p / q form as 8 / 9.

Step-by-step explanation:

We have to express 0.8(bar) in p / q form.

We know that 0.8(bar) is a non terminating repeating rational number.

For this we will first:

Let x = 0.8(bar)   ...(1)

Multiply both the sides by 10, we get that:

x × 10 = 0.8(bar) × 10

which is equal to:

10x = 8.8(bar)   ...(2)

Subtract (1) from (2), we get that:

10 x - x = 8.8(bar) - 0.8(bar)

9 x = 8

x =8 / 9

Therefore, 0.8(bar) can be written in p / q form as 8 / 9.
