Q. Write the repeating decimal as a fraction..313313313
Identify Repeating Pattern: Let's identify the repeating pattern in the decimal. The digits “313” repeat indefinitely.
Convert to Fraction: To convert the repeating decimal to a fraction, let's denote the repeating decimal as x:x=0.313313313...
Isolate Repeating Pattern: To isolate the repeating pattern, we can multiply x by 1000, since the pattern repeats every three decimal places: 1000x=313.313313313…
Subtract and Simplify: Now, we subtract the original x from 1000x to get rid of the repeating decimals: 1000x−x=313.313313313...−0.313313313...999x=313
Solve for x: Next, we solve for x by dividing both sides of the equation by 999:x=999313
Simplify Fraction: We can simplify the fraction by looking for a common divisor. In this case, the numerator and denominator do not have any common factors other than 1, so the fraction is already in its simplest form.
