Q. Write the repeating decimal as a fraction..119119119
Identify Repeating Pattern: Let's identify the repeating pattern in the decimal. The digits "119" repeat indefinitely.
Express as x: Express the repeating decimal as x: x=0.119119119…
Multiply by 1000: To isolate the repeating pattern, multiply x by 1000 because there are three digits in the repeating pattern: 1000x=119.119119119…
Subtract Original x: Now subtract the original x from 1000x to get rid of the decimal part: 1000x−x=119.119119119…−0.119119119…
Perform Subtraction: Perform the subtraction: 999x=119
Divide by 999: Divide both sides by 999 to solve for x: x=999119
Simplify Fraction: Simplify the fraction by looking for a common divisor. The numbers 119 and 999 do not have any common factors other than 1, so the fraction is already in its simplest form.
