Final answer:
The sum of the repeating digits in the decimal representation of 4/13, which is 0.307692307692..., is 27.
Step-by-step explanation:
The question asks about the sum of repeating digits in the decimal representation of 4/13.
First, we need to divide 4 by 13 using a calculator or long division, which will give us a repeating decimal.
Then we identify the repeating sequence of digits and sum them up.
When we divide 4 by 13, we get 0.307692307692..., and the repeating sequence of digits is 307692.
Summing these repeating digits, we have 3 + 0 + 7 + 6 + 9 + 2, which equals 27.
Hence, the sum of the repeating digits in 4/13 is 27.
