Answer 1

C)
`x=(17)/(33)`

Explanation:

0.51 repeating decimal

x= 0.51515151

multiply by 100 on both sides

100x = 51.515151.........

x= 0.515151...............

--------------------------------------------(subtract)

99x = 51

divide by 99 on both sides

`x=(51)/(99)`

divide both sides by 3

`x=(17)/(33)`
