Step-by-step solution for: Converting Repeating Decimals to Fractions Worksheet | Free ...
To solve the problem of converting repeating decimals to fractions, we will use a systematic approach. Let's go through each repeating decimal step by step.
1. Let \( x \) be the repeating decimal.
2. Multiply \( x \) by a power of 10 such that the repeating part aligns.
3. Subtract the original \( x \) from this new equation to eliminate the repeating part.
4. Solve for \( x \) to get the fraction.
Now, let's apply this method to each given repeating decimal.
---
#### Step 1: Let \( x = 0.\overline{4354} \).
\[ x = 0.435443544354\ldots \]
#### Step 2: Multiply by \( 10^4 = 10000 \) (since the repeating block has 4 digits).
\[ 10000x = 4354.435443544354\ldots \]
#### Step 3: Subtract the original \( x \) from this equation.
\[ 10000x - x = 4354.435443544354\ldots - 0.435443544354\ldots \]
\[ 9999x = 4354 \]
#### Step 4: Solve for \( x \).
\[ x = \frac{4354}{9999} \]
Thus, the fraction is:
\[ \boxed{\frac{4354}{9999}} \]
---
#### Step 1: Let \( x = 0.\overline{588} \).
\[ x = 0.588588588\ldots \]
#### Step 2: Multiply by \( 10^3 = 1000 \) (since the repeating block has 3 digits).
\[ 1000x = 588.588588588\ldots \]
#### Step 3: Subtract the original \( x \) from this equation.
\[ 1000x - x = 588.588588588\ldots - 0.588588588\ldots \]
\[ 999x = 588 \]
#### Step 4: Solve for \( x \).
\[ x = \frac{588}{999} \]
Simplify the fraction:
\[ \frac{588}{999} = \frac{196}{333} \]
Thus, the fraction is:
\[ \boxed{\frac{196}{333}} \]
---
#### Step 1: Let \( x = 0.\overline{680} \).
\[ x = 0.680680680\ldots \]
#### Step 2: Multiply by \( 10^3 = 1000 \) (since the repeating block has 3 digits).
\[ 1000x = 680.680680680\ldots \]
#### Step 3: Subtract the original \( x \) from this equation.
\[ 1000x - x = 680.680680680\ldots - 0.680680680\ldots \]
\[ 999x = 680 \]
#### Step 4: Solve for \( x \).
\[ x = \frac{680}{999} \]
Thus, the fraction is:
\[ \boxed{\frac{680}{999}} \]

\[ 1000x = 5484.484484484\ldots \]
#### Step 3: Subtract the original \( x \) from this equation.
\[ 1000x - x = 5484.484484484\ldots - 5.484484484\ldots \]
\[ 999x = 5479 \]
#### Step 4: Solve for \( x \).
