can someone pls answer this.....i will surely mark it as branliest and spam answers will be reported.....thank you

Answer 1

Answer:

Step-by-step explanation:

To express the nos. in the frm of p/q

1.0.5=5/10=1/2

2.let 10x=2.777....(1)

therefore, 100x=27.7777.....(2)

subtracting eq2 from eq1

100x=27.77

  -   x=  2.77

⇒99x=25

therefore x=99/25

3.let  x=4.121212.......(1)

therefore100x=412.121212.....(2)  

subtracting eq2 from eq1

100x=412.12

-     x=    4.12

⇒ 99x=408

therefore x=408/99=136/33

4.to find value of 4.12bar-0.27bar +0,5,

substituting the values of the same nos. we took out in the form of p/q

136/33-99/25 +1/2

=136
