Which of the following rational numbers can be expressed as a repeating decimal: 7/8, 5/12, 17/25, or 31/40?(1 point)

Answer 1

The rational numbers that can be expressed as a repeating decimal are the ones with denominators that are not divisible only by 2 or 5.

Out of the given options, only 7/8, 5/12, and 31/40 have denominators that are not divisible only by 2 or 5.

7/8 = 0.875 (terminating decimal)
5/12 = 0.416666... (repeating decimal)
17/25 = 0.68 (terminating decimal)
31/40 = 0.775 (terminating decimal)

Therefore, the rational numbers that can be expressed as a repeating decimal are 5/12. (B)

Answer 2

Express 713 as a repeating decimal. Mark the repeating digits with a bar.

Note: You will find the option to add a bar above text in the Geometry (∠) keyboard.
