Q. Write the repeating decimal as a fraction..726726726
Denote x as decimal: Let's denote the repeating decimal 0.726726726... as x.x=0.726726726...To isolate the repeating part, we multiply x by 1000 because there are three digits in the repeating sequence.1000x=726.726726726...
Multiply by 1000: Now, we subtract the original x from 1000x to get rid of the decimal part.1000x−x=726.726726726...−0.726726726...This simplifies to:999x=726
Subtract to eliminate decimal: To find the value of x, we divide both sides of the equation by 999.x=999726
Divide by 999: We can simplify the fraction by finding the greatest common divisor (GCD) of 726 and 999. The GCD of 726 and 999 is 3. x=999/3726/3x=333242
