Turn 3.8 repeating into a fraction

To turn into a fraction you shouls do such steps:

1 step. Set up an equation by representing the repeating decimal with a variable. Using your example, you will let x represent the repeating decimal 3.(8), so you have x=3.888... .

2 step. Identify how many digits are in the repeating pattern, or n digits. Multiply both sides of the equation from Step 1 by to create a new equation. Again, using your example, you see that the repeating pattern consists of just one digit: 8. Now multiply both sides of the equation by . Thus, you have or .

3 step. Subtract the equation in Step One from the equation in Step Two. Notice that when we subtract these equations, our repeating pattern drops off. Therefore, .

4 step. You now have an equation that you can solve for x and simplify as much as possible, using x as a fraction: . If you divide both sides by 9, you get . When simplified, you get that .
