The difference between the number formed by all the digits in decimal part and the number formed by digits that are not repeated, gives the numerator of the vulgar fraction and for its denominator the number formed by as many nines as there are recurring digits which are repeated followed by as many zeros as the number of non-repeating or non-recurring digits. To convert a Decimal to a Fraction follow these steps: Step 1: Write down the decimal divided by 1, like this: decimal 1 Step 2: Multiply both top and bottom. An easy trick to convert a repeating decimal to the fraction form is to write the repeating digits as the numerator over the same number of 9s. (ii)įor solving the problems on conversion of mixed recurring decimals into
Sides by 10 (Since number of digits without bar is 1)
Recurring decimals into vulgar fractions: 1. Worked-out examples for the conversion of mixed We get the required vulgar fraction in the lowest form. (vi) Suppose there are n-digits having bar, multiply both sides by 10 n.ĭivide both the sides of the equation by the coefficient of x. The number of digits having bar after the decimal point. (iii) Suppose there are n-digits without bar, multiply both sides by 10 n, so that only the repeating decimal digit is on the right side of the decimal point. The number of digits having no bar after the decimal point. Long Division Calculator with Decimals to convert a fraction to a decimal and see the work involved in the long division.The decimal form by removing the bar from the top and put it equal to x (any variable).
