To convert 2.77777777777 to a fraction:
Assume x = 2.7777777777......equation 1
Now, notice that the repeating digit is 7
multiply both sides of the equation by 10:
10x = 27.7777777777.......equation 2
Subtract equation 1 from equation 2 as follows:
10x - x = 27.7777777777 - 2.7777777777
9x = 25
Therefore x = 25/9
Based on this, 2.7 repeated can be written as a fraction = 25/9
