Explanation:

We first let 5.2108 (108 being repeated) be xx.

Since xx is recurring in 3 decimal places, we multiply it by 1000.

1000x = 5210.81081000x=5210.8108

Next, we subtract them.

1000x - x = 5210.8108 - 5.21081000xx=5210.81085.2108

999x = 5205.6999x=5205.6

Lastly, we divide both sides by 999 to get xx as a fraction.

x = 5201.6/999x=5201.6999

= 52016/9990=520169990

= 964/185=964185
