Fraction represents a whole and a fractional part. Decimals represent the fractional part of numbers. For example, 1/2, the numbers in decimal are expressed with a decimal point (.); for example, 1.09090909091. We are going to learn how to convert a decimal to a fraction.
The answer for 1.09090909091 as a fraction will be 12/11.
Converting a decimal to a fraction is a task for students that can be done easily. You can follow the steps mentioned below to find the answer.
Step 1: Identify the repeating part of the decimal. In this case, 0.090909... is the repeating part. Let x = 1.090909...
Step 2: Multiply x by 100 (since the repeating part has 2 digits) to move the decimal point: 100x = 109.090909...
Step 3: Subtract the original equation from this new one to eliminate the repeating part: 100x - x = 109.090909... - 1.090909... 99x = 108
Step 4: Solve for x by dividing both sides by 99: x = 108/99
Step 5: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 9: 108/99 = 12/11
Thus, 1.09090909091 can be written as a fraction 12/11.
