The question asks to convert the repeating decimal $1.236576576...$ into a fraction. The repeating block is '576'.
Let the number be x. So, $x = 1.236576576...$
Identify the non-repeating part ('23') and the repeating part ('576'). There are 2 digits before the repeating block and 3 digits in the repeating block.
Multiply x by $10^2 = 100$ to move the decimal point just before the repeating block:
$100x = 123.6576576...$ (Equation 1)
Multiply x by $10^{(2+3)} = 10^5 = 100000$ to move the decimal point to the end of the first repeating block:
$100000x = 123657.6576576...$ (Equation 2)
Subtract Equation 1 from Equation 2 to eliminate the repeating decimal part:
$100000x - 100x = 123657.6576576... - 123.6576576...$
$99900x = 123657 - 123$
$99900x = 123534$
Solve for x:
$x = \frac{123534}{99900}$
This result matches option 3.
What is the value of
$\frac{7}{9} - \frac{11}{12} + \frac{13}{16} - \frac{1}{8}$?
5 \(\frac{3}{4}\) + x + 2 \(\frac{1}{2}\) = 10 \(\frac{1}{8}\) Find the value of x.
Simplify the expression 441 ÷ \(\left[270 \div \frac{3}{7}+\left(17\div \frac{1}{3}\right)-\left(8\frac{1}{2}-\frac{5}{2}\right)\right]\)
