Who discovered repeating decimals?
Who discovered repeating decimals?
Decimal fractions had already been introduced by the Flemish mathematician Simon Stevin in 1586, but his notation was unwieldy. The use of a point as the separator occurs frequently in the Constructio. Joost Bürgi, the Swiss mathematician, between 1603 and 1611 independently invented a system…
How do you explain recurring decimals?
A recurring decimal exists when decimal numbers repeat forever. For example, means 0.333333… – the decimal never ends.
How do you solve a recurring decimal question?
We’ll walk through this step by step below.
- Step 1: Write out the equation. To convert a recurring decimal to a fraction, start by writing out the equation where (the fraction we are trying to find) is equal to the given number.
- Step 2: Cancel out the recurring digits.
- Step 3: Solve for 𝒳
- Step 4: Simplify the fraction.

What is the symbol for recurring?
A vinculum can indicate the repetend of a repeating decimal value: 1⁄7 = 0.
What is an example of a repeating decimal?
The definition of a repeating decimal is a fractional number in which one or more numbers after the decimal point repeats indefinitely. The fractional representation of 1/3, which is . 3333333 (with the 3 repeating forever) is an example of a repeating decimal.
Are recurring decimals rational?
A terminating decimal can be written as a fraction by using properties of place value. A common question is “are repeating decimals rational numbers?” The answer is yes!
Is 0.125 a repeating decimal?

Who is the father of decimal?
The Jewish mathematician Immanuel Bonfils used decimal fractions around 1350, anticipating Simon Stevin, but did not develop any notation to represent them. The Persian mathematician Jamshīd al-Kāshī claimed to have discovered decimal fractions himself in the 15th century.
What is an example of a recurring decimal?
For example, 0.75. A recurring decimal exists when decimal numbers repeat forever. For example, \\ (0. \\dot {3}\\) means 0.333333… – the decimal never ends. Dot notation is used with recurring decimals.
How do you know if a decimal will terminate or recur?
To find out whether a fraction will have a terminating or recurring decimal, look at the prime factors of the denominator when the fraction is in its most simple form. If they are made up of 2s and/or 5s, the decimal will terminate. If the prime factors of the denominator contain any other numbers, the decimal will recur.
What is the difference between a dot notation and a recurring decimal?
Some decimals terminate, which means the decimals do not recure, they just stop. For example, 0.75. A recurring decimal exists when decimal numbers repeat forever. For example, (0. dot {3}) means 0.333333… – the decimal never ends. Dot notation is used with recurring decimals.
How do you convert a fraction to a recurring decimal?
So, Another way to convert a fraction to a recurring decimal is to treat the fraction like a division and use some method of division to divide the numerator by the denominator. Here we will use the bus stop method. as a decimal. We set up the bus stop method as follows, with several zeros after the decimal place.
