To convert recurring decimals to fractions, you need to follow a few steps. First, identify the recurring decimal pattern. This pattern is a sequence of one or more digits that repeats indefinitely.
Next, let's take an example to understand the steps better. Let's say we have the recurring decimal 0.3333...
Then, we need to assign a variable to the repeating digits. In our example, we can assign the variable 'x' to the repeating pattern, which is 3 in this case.
After assigning the variable, we need to create an equation to solve for it. In our example, we can write the equation 'x = 0.3333...'
Simplifying the equation, we can multiply both sides by 10 to eliminate the decimal point. This gives us the equation '10x = 3.3333...'
Next, we need to subtract the original equation from the simplified equation. This cancels out the recurring decimal pattern. So, '10x - x = 3.3333... - 0.3333...'
Simplifying the equation further, we have '9x = 3.'
To find the value of 'x', we divide both sides of the equation by 9. So, 'x = 3/9.'
Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor. In our example, 3/9 can be simplified to 1/3.
So, the recurring decimal 0.3333... is equal to the fraction 1/3.
Converting a recurring decimal into a fraction can be a useful skill to have in mathematics. Recurring decimals, also known as repeating decimals, are numbers that have a pattern in their decimal representation. To convert a recurring decimal into a fraction, there are a few steps you can follow.
The first step is to identify the part of the decimal that is repeating. This is usually indicated by a line or bracket over the repeating part. For example, in the recurring decimal 0.333..., the digits 3 are repeating.
Next, you need to determine the number of repeating digits in the decimal. This can be done by counting the number of digits in the repeating part. In the example 0.333..., there is only one repeating digit, which is 3.
After identifying the repeating part and the number of repeating digits, the next step is to create an equation. Let's denote the repeating decimal as x. To convert it into a fraction, multiply both sides of the equation by a power of 10 that eliminates the decimal part of the recurring decimal. In the case of 0.333..., we can multiply the equation by 10 to get 10x = 3.333....
Now we can use algebraic manipulation to solve for x. Subtracting the original equation from the multiplied equation, we get 10x - x = 3.333... - 0.333..., which simplifies to 9x = 3.
To isolate x, divide both sides of the equation by 9. This gives us x = 3/9, which can be simplified further. Both the numerator and denominator can be divided by their greatest common divisor, which is 3. Dividing 3 by 3 gives us 1, and dividing 9 by 3 gives us 3. Therefore, the fraction equivalent of the recurring decimal 0.333... is 1/3.
Finally, it's important to note that not all recurring decimals can be converted into fractions. Some repeating decimals may have patterns that are more complex, making it difficult to find an exact fraction equivalent. In such cases, the decimal representation is often the preferred form.
How do you turn 0.33333 into a fraction?
Converting a decimal number like 0.33333 into a fraction is a straightforward process. To do this, we need to determine the decimal's place value and represent it as a ratio of two integers.
Firstly, let's consider the decimal 0.33333. If we inspect it closely, we can see that the digit 3 in the thousandth place repeats infinitely.
Now, to convert 0.33333 into a fraction, we can assign a variable to the decimal. Let's assume the decimal is represented by the variable 'x'.
So, we can express the decimal 0.33333 as:
x = 0.33333
To remove the repeating decimal, we multiply both sides of the equation by 10, which will shift the decimal place one position to the right:
10x = 3.33333
Next, we subtract the original equation from this new equation:
10x - x = 3.33333 - 0.33333
Simplifying the equation:
9x = 3
Now, we can solve for x by dividing both sides of the equation by 9:
x = 3/9
Since both 3 and 9 are divisible by 3, we can simplify the fraction to:
x = 1/3
Therefore, we can conclude that the decimal 0.33333 can be represented as the fraction 1/3.
The shortcut to convert a repeating decimal to a fraction involves a simple mathematical technique.
To begin, let's understand what a repeating decimal is. A repeating decimal is a decimal number that has a repeating pattern of digits, such as 0.3333... or 0.262626...
The first step in converting a repeating decimal to a fraction is to identify the repeating pattern. This can be done by observing the digits that repeat continuously.
Next, we will represent the repeating pattern as a variable, let's say 'x'. For example, if the repeating pattern is 0.3333..., we can represent it as x = 0.3333...
Now, multiply both sides of the equation by a power of 10 that will "shift" the repeating pattern to the left of the decimal point. For example, in the case of 0.3333..., we can multiply both sides by 10, resulting in 10x = 3.3333....
After that, we will subtract the original equation (x = 0.3333...) from the equation obtained in the previous step (10x = 3.3333...). This will eliminate the repeating pattern. In this example, subtracting x from 10x gives us 10x - x = 3.3333... - 0.3333..., simplifying to 9x = 3.
Finally, solve for 'x' by dividing both sides of the equation by the coefficient of 'x'. In this case, dividing 9x = 3 by 9 gives us x = 1/3.
Therefore, by following this shortcut, we have successfully converted the repeating decimal 0.3333... to the fraction 1/3.
This shortcut can be applied to convert any repeating decimal to a fraction quickly and efficiently.
2.1 recurring can be expressed as a fraction by converting the recurring decimal into its equivalent fraction form. To do this, we need to understand the concept of recurring decimals. A recurring decimal is a decimal number in which one or more digits repeat indefinitely.
To convert 2.1 recurring into a fraction, we first need to identify the recurring part. In this case, the decimal "1" infinitely repeats. We denote the recurring part by placing a bar over it, so the recurring part of 2.1 recurring is simply "1".
Next, we need to determine the number of decimal places the recurring part occupies. In this case, the recurring part "1" sits in the tenths place. Since there is only one recurring digit in the tenths place, we can express it as a fraction with a numerator equal to the recurring digit and a denominator equal to the place value it occupies.
Therefore, 2.1 recurring can be represented as the fraction 21/10. This fraction can also be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1 in this case.
In conclusion, 2.1 recurring as a fraction is 21/10.
