Question

express 2.9 (9 bar) in the form of p/q​

Answer 1

Step-by-step explanation:

2.9( bar) = 2.9999999.....

let x = 2.9999........eq 1

multiply both sides by 10

subtract eq 2 from eq 1

=10x - x = 29.9999 - 2.9999

=9x = 27

=x = 27/9

therefore,2.9(bar) in p/q is 27/9.

Answer 2

Answer:

27/9=3/1

Step-by-step explanation:

2.9(9 bar)=2.999.....

let x be 2.999....

x=2.999....-eq1

Multiply 10 to both sides

(since 1 digit is repeated)

10x=29.999...-eq2

Subtract eq2 and eq1

10x-x=29.999....-2.999....

9x=27

x=27/9

x=3/1
