1 5 repeating as a fraction
What is 1.5 repeated as a fraction?
1.5 equals 14 9 as an improper fraction or 15 9 as a mixed number. How do you turn 1. 5 repeating into a fraction? Step 1: To convert 1. 5 repeating into a fraction, begin writing this simple equation: Step 2: Notice that there is 1 digits in the repeating block (5), so multiply both sides by 1 followed by 1 zeros, i.e., by 10.
How do you convert a repeating decimal into a fraction?
Namely, to convert a repeating decimal into a fraction, multiply the repeating decimal by some power of 10—that is, by 10, 100, 1000, or whatever is needed—so that we can then subtract the repeating decimal part off of this new number.
How to convert repeating decimals to fractions?
To convert repeating decimals to fractions: Let [Math Processing Error] x be the repeating decimal. Find the repeating digit (s) by examining the repeating decimal. Find [Math Processing Error] 10 x (multiply the repeating decimal by 10) if there is one repeating digit, find [Math Processing Error] 100 x if there are two ... More items...
Is repeating decimal irrational?
All rational numbers have either finite decimal expansions (i.e., are regular numbers; e.g., ) or repeating decimals (e.g., ). However, irrational numbers, such as neither terminate nor become periodic. Numbers such as 0.5 are sometimes regarded as repeating decimals since .

division to check this and see that 3 ÷ 12 is 0.25 or 2*10-1 + 5*10-2. Conversely, one can write any terminating decimal as a fraction by simply using a denominator made of 2s and 5s. For example, the decimal 0.83564125 can be written as a fraction whose denominator is 28*58 or 100,000,000, giving us the fraction 100,000,000 83,564,125.
