The notation (0.67\\overline{7}) means that the digits &#8220;67&#8221; are followed by an infinite series of the digit &#8220;7&#8221; (i.e., 0.677777\u2026).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Define the Decimal as a Variable<\/h3>\n\n\n\n<p>Let (x = 0.67\\overline{7}).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Eliminate the Repeating Part<\/h3>\n\n\n\n<p>To eliminate the repeating part, we can multiply (x) by a power of 10 that moves the decimal point to the right, covering one full cycle of the repeating digits. Since the &#8220;7&#8221; repeats after two digits (&#8220;67&#8221;), we multiply by (1000) (two for &#8220;67&#8221; and one for the repeat):<\/p>\n\n\n\n<p>[<br>1000x = 677.7777\\overline{7}<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Set Up a System of Equations<\/h3>\n\n\n\n<p>Next, we can create a second equation without the repeating part. Multiply (x) by (10) to cover just the &#8220;67&#8221;:<\/p>\n\n\n\n<p>[<br>10x = 6.7777\\overline{7}<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Subtract the Two Equations<\/h3>\n\n\n\n<p>Now, we subtract the second equation from the first to eliminate the repeating part:<\/p>\n\n\n\n<p>[<br>1000x &#8211; 10x = 677.7777\\overline{7} &#8211; 6.7777\\overline{7}<br>]<\/p>\n\n\n\n<p>This simplifies to:<\/p>\n\n\n\n<p>[<br>990x = 670<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Solve for (x)<\/h3>\n\n\n\n<p>Next, divide both sides by (990):<\/p>\n\n\n\n<p>[<br>x = \\frac{670}{990}<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Simplify the Fraction<\/h3>\n\n\n\n<p>To simplify (\\frac{670}{990}), we can find the greatest common divisor (GCD) of (670) and (990). The prime factorization shows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>(670 = 2 \\times 5 \\times 67)<\/li>\n\n\n\n<li>(990 = 2 \\times 3^2 \\times 5 \\times 11)<\/li>\n<\/ul>\n\n\n\n<p>The common factors are (2) and (5). The GCD is (10). Now, we divide both the numerator and the denominator by (10):<\/p>\n\n\n\n<p>[<br>\\frac{670 \\div 10}{990 \\div 10} = \\frac{67}{99}<br>]<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p>Thus, the simplified fraction of the repeating decimal (0.67\\overline{7}) is:<\/p>\n\n\n\n<p>[<br>\\boxed{\\frac{67}{99}}<br>]<\/p>\n\n\n\n<p>This fraction is now in its simplest form, representing the original repeating decimal accurately.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rewrite as a simplified fraction. 0.67 where 7 repeats forever The Correct Answer and Explanation is: To convert the repeating decimal (0.67\\overline{7}) into a simplified fraction, we can follow a systematic approach.
