Express 811 as a repeating decima

Answer 1

To express 811 as a repeating decimal, we can first divide 811 by 1000:

811 ÷ 1000 = 0.811

Since 811 is a whole number, we can rewrite it as 811/1. Then, to convert the fraction 811/1 into a repeating decimal, we can multiply both the numerator and denominator by the same power of 10, which in this case is 1000:

(811/1) × (1000/1000) = 811000/1000 = 811

Now, we can express 811 as a repeating decimal by placing a horizontal line (vinculum) over the repeating part, which is 811:

811 = 0.811

Thus, 811 can be expressed as a repeating decimal as 0.811.
