Q. Convert the following repeating decimal to a fraction in simplest form..15Answer:
Set up equation with x: Let x=0.151515...To convert the repeating decimal to a fraction, we can set up an equation using x to represent the repeating decimal. Since the digits 15 repeat, we will multiply x by 100 to shift the decimal two places to the right.
Multiply by 100: Multiplying x by 100, we get:100x=15.151515...Now we have two expressions: x=0.151515... and 100x=15.151515...Subtracting the first equation from the second will help us eliminate the repeating part.
Subtract equations: Subtract the first equation from the second:100x−x=15.151515...−0.151515...99x=15Now we can solve for x by dividing both sides of the equation by 99.
Solve for x: Dividing both sides by 99, we get:x=9915Now we need to simplify the fraction to its simplest form.
Simplify the fraction: To simplify the fraction, we find the greatest common divisor (GCD) of 15 and 99. The GCD of 15 and 99 is 3. Dividing both the numerator and the denominator by 3, we get: x=(315)/(399)x=335
