Q. Write the repeating decimal as a fraction..579579579
Identify repeating decimal: Let's identify the repeating part of the decimal. The digits 579 are repeating.
Represent as x: Let's represent the repeating decimal as x: x=0.579579579…
Shift decimal point: To convert the repeating decimal to a fraction, we multiply x by 1000 (since there are three digits in the repeating sequence) to shift the decimal point three places to the right: 1000x=579.579579579…
Subtract original x: Now, we subtract the original x from 1000x to get rid of the repeating decimals: 1000x−x=579.579579579…−0.579579579…
Solve for x: This subtraction gives us: 999x=579
Find GCD: Now, we solve for x by dividing both sides of the equation by 999: x=999579
Simplify fraction: We can simplify the fraction by finding the greatest common divisor (GCD) of 579 and 999. The GCD of 579 and 999 is 3.
Final result: Divide both the numerator and the denominator by the GCD to simplify the fraction: x=999/3579/3
Final result: Divide both the numerator and the denominator by the GCD to simplify the fraction: x=3579/3999 After simplification, we get: x=333193
