Final Answer:
The choice equal to the repeating decimal 0.4 is A. 4/10.
Step-by-step explanation:
When converting a decimal to a fraction, 0.4 can be written as 4/10. Although B (0.444) seems similar, it represents a different value as it doesn’t precisely match 0.4, whereas choice A correctly represents the decimal as a fraction equivalent.
The decimal 0.4 represents 4 tenths, which is numerically equivalent to the fraction 4/10. This fraction can be further simplified to 2/5 by dividing both the numerator and denominator by their greatest common factor, which in this case is 2. Hence, A (4/10) is the choice equivalent to the repeating decimal 0.4.
Correct Answer: A. 4/10
