The correct Answer is:
To solve the expression \( 2.\overline{6} - 0.\overline{82} \), we will first convert the repeating decimals into fractions. ### Step 1: Convert \( 2.\overline{6} \) to a fraction Let \( x = 2.\overline{6} \). To eliminate the repeating part, we can multiply by 10: \[ 10x = 26.\overline{6} \] Now, subtract the original equation from this new equation: \[ 10x - x = 26.\overline{6} - 2.\overline{6} \] \[ 9x = 24 \] \[ x = \frac{24}{9} = \frac{8}{3} \] ### Step 2: Convert \( 0.\overline{82} \) to a fraction Let \( y = 0.\overline{82} \). To eliminate the repeating part, we can multiply by 100: \[ 100y = 82.\overline{82} \] Now, subtract the original equation from this new equation: \[ 100y - y = 82.\overline{82} - 0.\overline{82} \] \[ 99y = 82 \] \[ y = \frac{82}{99} \] ### Step 3: Subtract the two fractions Now we need to calculate \( 2.\overline{6} - 0.\overline{82} \): \[ x - y = \frac{8}{3} - \frac{82}{99} \] To subtract these fractions, we need a common denominator. The least common multiple (LCM) of 3 and 99 is 99. Convert \( \frac{8}{3} \) to have a denominator of 99: \[ \frac{8}{3} = \frac{8 \times 33}{3 \times 33} = \frac{264}{99} \] Now we can subtract: \[ \frac{264}{99} - \frac{82}{99} = \frac{264 - 82}{99} = \frac{182}{99} \] ### Final Answer Thus, the result of \( 2.\overline{6} - 0.\overline{82} \) is: \[ \frac{182}{99} \]
