Understanding the Problem

When dealing with recurring decimals, it's essential to convert them into fractions to simplify the expression and make it easier to work with. In this case, we're given the recurring decimal $$1 . \overline{7}$$ and asked to express it as a fraction in its simplest form.

The Concept of Recurring Decimals

A recurring decimal is a decimal number that has a repeating pattern of digits. In the case of $$1 . \overline{7}$$, the digit 7 is repeating indefinitely. To convert this recurring decimal into a fraction, we can use algebraic manipulation.

Converting Recurring Decimals to Fractions

Let's denote the recurring decimal as x, so x = $$1 . \overline{7}$$. To convert this into a fraction, we can multiply both sides of the equation by 10 to shift the decimal point one place to the right. This gives us:

10x = $$10 . \overline{7}$$

Now, we can subtract the original equation from this new equation to eliminate the recurring decimal:

10x - x = $$10 . \overline{7}$$ - $$1 . \overline{7}$$

This simplifies to:

9x = 9

Now, we can solve for x by dividing both sides of the equation by 9:

x = 1

However, this is not the correct answer, as we know that $$1 . \overline{7}$$ is a recurring decimal. Let's try a different approach.

Using Algebraic Manipulation

10x = $$10 . \overline{7}$$

Now, we can subtract the original equation from this new equation to eliminate the recurring decimal:

10x - x = $$10 . \overline{7}$$ - $$1 . \overline{7}$$

This simplifies to:

9x = 9.7

Now, we can solve for x by dividing both sides of the equation by 9:

x = 1.07

However, this is still not the correct answer, as we know that $$1 . \overline{7}$$ is a recurring decimal. Let's try a different approach.

Using a Different Algebraic Manipulation

10x = $$10 . \overline{7}$$

Now, we can subtract the original equation from this new equation to eliminate the recurring decimal:
