Question

Which of the following numbers can be expressed as repeating decimals?

a) 5
b) 4
c) 15
d) 1/3

Answer 1

The number that can be expressed as a repeating decimal among the given options is 1/3; whole numbers like 5, 4, and 15 do not have repeating decimals.

Step-by-step explanation:

The student has asked which of the following numbers can be expressed as repeating decimals: a) 5 b) 4 c) 15 d) 1/3. To answer this, we need to consider that whole numbers like 5, 4, and 15 do not have repeating decimals since they can be written without a fractional component. However, fractions can sometimes result in repeating decimals when they cannot be converted to a finite decimal form. The fraction 1/3 is a classic example that yields a repeating decimal of 0.333... indefinitely. Therefore, the answer is d) 1/3.
