Question
Which of the following fractions is a terminating
decimal?Solution
Concept -we need to check if the denominator (after simplification) contains only the prime factors 2 and/or 5. A fraction has a terminating decimal if and only if, in its simplest form, the denominator has no prime factors other According to the option- =5/8 The denominator 8 can be factored into 23. Since it contains only the prime factor. 5/8 is a terminating decimal.
