0.57 can b written as p/q, q is not equal to 0 as:
a) 26/45 b) 13/27 c)13/29 d) 57/99
I think there is some mistake in your question.The number 0.57 must be either
CASE FIRST
If your question has , then the answer is given below.
Let x = = 0.5777....
⇒ 10x = 5.7777.............. .............(1)
⇒ 100x = 57.7777.......... ..............(2)
subtracting eq.(1) from eq.(2), we get,
90x = 57.7777..... - 5.7777......
⇒ 90x = 52
so option (a) is correct.
CASE SECOND
If your question has , then the answer is given below.
Let x = =0.57575757......... ............(1)
⇒ 100x = 57.57575757.............. .............(2)
subtracting eq.(1) from (2), we get,
99x =57.5757...... - 0.5757.......
⇒ 99x =57
So option (d) is correct in this case.
