\r\n To convert the decimal 0.18<\/strong> into a simplified fraction,\r\n you first write it as\r\n 18\/100<\/strong>\r\n (since the 8 is in the hundredths place).\r\n <\/p>\r\n\r\n

\r\n Then, you simplify this fraction by dividing both the numerator\r\n (18)<\/strong> and the denominator\r\n (100)<\/strong>\r\n by their greatest common divisor, which is\r\n 2<\/strong>.\r\n <\/p>\r\n\r\n

\r\n This mathematical operation gives you the finalized, reduced fraction of\r\n 9\/50<\/strong>.\r\n <\/p>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\r\n Converting a terminating (simple) decimal like \r\n 0.18<\/strong> into a fraction follows a reliable, \r\n three-step mathematical process.\r\n <\/p>\r\n\r\n

Step 1: Write as a Fraction over 1<\/h3>\r\n\r\n

\r\n The first step is to place the decimal number over a denominator of 1 to create \r\n an initial, improper fraction form.\r\n <\/p>\r\n\r\n

\r\n 0.18 = 0.18 \/ 1\r\n <\/p>\r\n\r\n

Step 2: Remove the Decimal<\/h3>\r\n\r\n

\r\n To remove the decimal point without changing the number's value, we must multiply \r\n both the numerator (top) and the denominator (bottom) by 10 for every digit to the \r\n right of the decimal point. In 0.18<\/strong>, \r\n there are two digits (the 1 and the 8), so we multiply by \r\n 102<\/sup><\/strong>, or 100.\r\n <\/p>\r\n\r\n

\r\n (0.18 \u00d7 100) \/ (1 \u00d7 100) = 18 \/ 100\r\n <\/p>\r\n\r\n

\r\n Now we have a correct representation:\r\n 18 \/ 100<\/strong>.\r\n <\/p>\r\n\r\n

Step 3: Simplify the Fraction (Find the Simplest Form)<\/h3>\r\n\r\n

\r\n Most math and scientific applications require you to simplify the fraction to its \r\n lowest terms. To do this, find the Greatest Common Divisor (GCD) for both the \r\n numerator (18) and the denominator (100). The GCD of 18 and 100 is \r\n 2<\/strong>. We divide both numbers by 2.\r\n <\/p>\r\n\r\n

\r\n

\r\n 18 \u00f7 2 = 9<\/strong>\r\n <\/p>\r\n\r\n

\r\n 100 \u00f7 2 = 50<\/strong>\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n The final, simplest form of \r\n 0.18<\/strong> as a fraction is:\r\n <\/p>\r\n\r\n

\r\n \r\n 9 \/ 50\r\n <\/strong>\r\n <\/div>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\r\n A common point of confusion is when the decimal is repeating, often written with a bar over it as \r\n 0.18\u0305<\/span> \r\n (or 0.181818...<\/span>). \r\n The method for converting a repeating decimal is entirely different from the process for a simple decimal.\r\n <\/p>\r\n\r\n

\r\n Here is how we calculate 0.18 repeating as a fraction:\r\n <\/p>\r\n\r\n

Step 1: Set up the Equation<\/h3>\r\n\r\n

\r\n We start by defining a variable x<\/strong> and setting it equal to the repeating decimal.\r\n <\/p>\r\n\r\n

\r\n x = 0.181818...\r\n <\/p>\r\n\r\n

Step 2: Multiply to Shift the Repeat<\/h3>\r\n\r\n

\r\n To eliminate the repeating part, we want to shift the repeat one full cycle to the left. \r\n Since two digits (the 18<\/strong>) repeat, we multiply the entire equation by 100.\r\n <\/p>\r\n\r\n

\r\n 100x = 18.181818...\r\n <\/p>\r\n\r\n

Step 3: Subtract the Original Equation<\/h3>\r\n\r\n

\r\n Now, subtract the original equation (from Step 1) from the new, multiplied equation (from Step 2). \r\n This subtraction isolates the integer value:\r\n <\/p>\r\n\r\n

\r\n
100x = 18.181818...<\/div>\r\n
-x =    0.181818...<\/div>\r\n
-----------------<\/div>\r\n
99x = 18<\/div>\r\n <\/div>\r\n\r\n

Step 4: Solve for x and Simplify<\/h3>\r\n\r\n

\r\n Finally, solve for x<\/strong> and simplify the resulting fraction. \r\n Divide both sides by 99:\r\n <\/p>\r\n\r\n

\r\n x = 18\/99\r\n <\/p>\r\n\r\n

\r\n We can simplify this fraction by finding the GCD. The GCD of 18 and 99 is \r\n 9<\/strong>.\r\n <\/p>\r\n\r\n

\r\n 18 \u00f7 9 = 2
\r\n 99 \u00f7 9 = 11\r\n <\/p>\r\n\r\n

\r\n Therefore, 0.18 repeating as a fraction is 2\/11.\r\n <\/p>\r\n\r\n<\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
