Here are the following factors for 51 and 100:
51= 1, 3, 17, 51
100=1, 2, 4, 5, 10, 20, 25, 50, 100
Since none of the numbers that go into 51 go into 100
(1 doesn't count) 51/100 is the correct answer, and cannot be put into lower terms.

Answer:

23/45

Step-by-step explanation:

let x equal the decimal. set up two equations such that the digits after the decimal point are identical.

100x=51.11111..

10x=5.1111..

Subtracting the two equations, we have:

90x=46

x=46/90

x=23/45
