Is 2/13 a repeating decimal

Mathematics
1 answer:
Cloud [144]3 years ago
8 0

The denominator 13 cannot be factored so that only 2's and 5's show up, so this means that 2/13 is a non-terminating decimal. Therefore, this decimal repeats itself

Use a calculator to see that: 2/13 = 0.153846  153846  153846 ....

The spaces are put in to help make the number more readable. Note how the "153846" keeps repeating forever
