Loads of them. A half, a quarter, an eighth, a tenth, a twentieth, a fortieth, a fiftieth, a hundredth.
To check, write the fraction out. For example a quarter is written 1/4. All that means is 1 divided by 4. Divide 1 by 4 and you get 0.25 - a quarter.

Is it possible to express every decimal as a fraction?
Not all decimals can be expressed as fractions. Only terminating and recurring decimals can be expressed as fractions. eg a recurring decimal: 0.3333333... = 1/3 A terminating decimal: 0.125 = 1/8 A decimal that does not recurr or terminate, cannot be expressed as a fraction. eg Pi = 3.141592654... Pi can not be expressed as a fraction as it does not recurr or terminate. It can only be approximated to a fraction. eg Pi ≈ 355/113 but is correct to 6 decimal places.
How does the number of decimal places in the product relate to the number of decimal places in the factors?
The number of decimal places for the product will be the summation of the amount of decimal places of the 2 factors. For example, if your products have 2 decimals each to the right of zero then the product will have an answer with 4 decimals to the right of zero.

Is it easier to work with fractions or decimals?
Decimals until you get to values with over nine decimal places, then fractions are more exact
How fractions are related to repeating decimals and terminating decimals?
Fractions are related to repeating decimals in the sense that a fraction can be represented as a repeating decimal if the denominator has prime factors other than 2 or 5. For example, 1/3 can be represented as 0.3333..., with the 3s repeating infinitely. Terminating decimals, on the other hand, are fractions that have denominators which are powers of 10. For example, 1/4 can be represented as 0.25, which terminates after two decimal places.
How to turn a fraction to a decimal?
, divide the numerator by the denominator. To change terminal decimals into fractions, count the number of decimal places, put the decimal's digits over 1 followed by the proper number of zeroes.
Can an irrational number be a decimal?
If you write an irrational number as a decimal, you would have an infinite number of decimal places, and the digits wouldn't repeat. That is, if you divide 1 by 7 for example, you get the pattern 0.142857 142857 142857... repeating over and over; this won't happen with an irrational number.All irrational numbers are decimals which can not be expressed as fractions
Is equivalent decimals are decimals that have the same value true?
The decimals with the same number of decimal places are called like decimals. Equivalent decimals are decimal numbers that have the same value. For example, 3.42, 6.05 are like decimals as they have two decimal places. For example, 0.3 and 0.30 are equivalent decimals as they present the same value.
How do you make fractions into decimals and percentages?
Divide the numerator of the fraction by the denominator, using long division if necessary, to get a decimal fraction. Move the decimal point two places to the right and append a percent symbol for a percentage.
How does the number of decimal places in the product relate to the number of decimal places in the factors?
The number of decimal places for the product will be the summation of the amount of decimal places of the 2 factors. For example, if your products have 2 decimals each to the right of zero then the product will have an answer with 4 decimals to the right of zero.
Which method you prefer for converting decimals to percents using equivalent fractions or multiplying by 100 why?
Multiplying by 100 is easier. Just move the decimal point two places to the right.
