What’s 2.33333333333 as a Fraction ?

2.33333333333 as a fraction is approximately 2,333,333.33633/1,000,000,000. This fraction represents the repeating decimal as a ratio of two whole numbers, indicating that 2.33333333333 is approximately 2,333,333.33633 parts out of 1,000,000,000.

Repeating Decimals vs. Terminating Decimals:

Before we dive into the conversion process, let’s differentiate between repeating decimals and terminating decimals. Terminating decimals have a finite number of digits after the decimal point, such as 2.75. Repeating decimals, on the other hand, have a repeating pattern of digits after the decimal point, such as 1.666…, where the “6” repeats infinitely.

Understanding Repeating Decimals:

Repeating decimals are typically expressed using a vinculum, which is a horizontal line placed over the repeating portion of the digits. In the case of 2.33333333333, it can be written as 2.3 with a vinculum over the “3,” indicating that the “3” repeats infinitely.

Step 1: Define the Variables:

To convert a repeating decimal to a fraction, we’ll need to introduce some variables:

• Let x = 2.33333333333 (the repeating decimal).
• Let y = 2.333333333333… (with the “3” repeating infinitely).

Step 2: Subtract x from y:

Now, we subtract x from y to eliminate the repeating portion:

y – x = 2.333333333333… – 2.33333333333

This subtraction will cancel out the repeating part of the decimal.

Step 3: Solve for y:

Solving for y gives us:

y – x = 2.333333333333… – 2.33333333333

y – x = 0.000000000003…

Step 4: Convert the Decimal into a Fraction:

To convert the decimal into a fraction, we’ll represent it as a fraction over a power of 10:

0.000000000003… = 3 / (10^12)

Now, we have y – x = 3 / (10^12).

Step 5: Isolate y:

To find y, we add x to both sides of the equation:

y = x + (3 / (10^12))

y = 2.33333333333 + (3 / (10^12))

Step 6: Simplify the Fraction:

Now, we simplify the fraction 3 / (10^12):

3 / (10^12) = 3 / 1,000,000,000,000

So, y = 2.33333333333 + (3 / 1,000,000,000,000)

Step 7: Find a Common Denominator:

To add the two terms, we need a common denominator:

y = (2.33333333333 * 1,000,000,000,000 / 1,000,000,000,000) + (3 / 1,000,000,000,000)

Step 8: Perform the Addition:

Now, we can add the fractions:

y = 2,333,333,333.33 / 1,000,000,000,000 + 3 / 1,000,000,000,000

y = (2,333,333,333.33 + 3) / 1,000,000,000,000

y = 2,333,333,336.33 / 1,000,000,000,000

Step 9: Simplify the Fraction Further:

We can simplify this fraction by dividing both the numerator and denominator by 1,000:

y = (2,333,333.33633 / 1,000,000,000)

Now, we have successfully converted the repeating decimal 2.33333333333 to its fractional form:

y = 2,333,333.33633 / 1,000,000,000
