Answer 2

Answer:

43/9

Step-by-step explanation:

Let x = 0.4777.........

Now we have to bring the 4 from the decimal portion to to the other side

Now

10x = 4.777...........                                   1

The digit 7 is repeating

So, multiply 10 on both sides.

100x = 47.777......                                  2

Subtract 2 - 1

100x -10x = 47.777.........  -   4.777............

90x  = 47 - 4

90x  = 43

x     = 43/90
