What causes a decimal to repeat?
Repeating decimals occur when a positive whole number is divided by another positive whole number and the dividend is not exactly divisible by its divisor. Divisors such as 3, 7, 9 and 11 usually produce repeating decimals.
How do you fix a repeating decimal?
Converting repeating decimals to fractions
- Let x equal the repeating decimal you are trying to convert to a fraction.
- Examine the repeating decimal to find the repeating digit(s).
- Place the repeating digit(s) to the left of the decimal point.
- Place the repeating digit(s) to the right of the decimal point.
Is 0.22 repeating a rational number?
A repeating decimal is not considered to be a rational number it is a rational number. (I see the decimal 0.25 as repeating since it can be written 0.25000…) Also any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number. Let me illustrate with an example.

How do you divide a number with a repeating decimal?
Insert a decimal point in the quotient (answer) space, exactly above the decimal point in the number under the division bar. Divide until the remainder is zero, or until you have enough decimal places in your answer. You can also stop if the remainder repeats because this indicates that your answer is a repeating decimal.
How do you do long division with decimal numbers?
Do long division with decimal numbers and see the work for the calculation step-by-step. Enter positive or negative decimal numbers for divisor and dividend and calculate a quotient answer. If the number you’re dividing by has a decimal, move the decimal point all the way to the right counting the number of places you’ve moved it to.
What is the most commonly encountered repeating decimal?

How do you divide a number with a decimal point?
Then move the decimal point in the number you’re dividing the same number of places to the right. Insert a decimal point in the quotient (answer) space, exactly above the decimal point in the number under the division bar. Divide until the remainder is zero, or until you have enough decimal places in your answer.
