Question

Express 0.255555...... in the form p/q, where p and q are integers and q ≠ 0

Answer 1

Answer:

23/90

Step-by-step explanation:

let 0.255555  be any letter e.g y

then  Y=0.255555

10Y =  10*0.255555....

10Y  =  2.555555

    10Y  =  2.555555

-     Y   =   0.255555

        9Y =  2.3

    9Y/9  =2.3/9

      Y  =  2.3/9 * 10/10

       Y=  23/90
