Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out. Step by step guide to Convert Repeating Decimals into FractionsĪ decimal number with a digit (or group of digits) that repeats forever is a “repeating decimal.” The repeating digits are indicated by drawing a bar over them as in \(\color\) Exercises for Converting Repeating Decimals to Fractions Convert each decimal to a fraction. 3 repeating into a fraction, begin writing this simple equation: Step 2: Notice that there is 1 digits in the repeating block (3), so multiply both sides by 1 followed by 1 zeros, i.e., by 10.
Converting recurring decimals to fractions how to#
This article teaches you how to Convert Repeating Decimals to Fractions in a few simple steps. + Ratio, Proportion & Percentages Puzzles.(Again, notice how the repeated parts must align to subtract out. Since 100 n and 10 n have the same fractional part, their difference is an integer. (The repeating parts are the same, so they subtract out.) ġ0 n and n have the same fractional part, so their difference is an integer.ġ00 n and n have the same fractional part, so their difference is an integer. Every infinite repeating decimal can be expressed as a fraction.įind the fraction represented by the repeating decimal.
