5003 Praxis Practice Test Practice Question
Which of the following statements is true about the number 90?
Correct Answer: B
Rationale: Option B accurately identifies that 6 and 15 are factors of 90, as 90 divided by both yields whole numbers (15 and 6, respectively).
Option A is incorrect because while 10 is a factor of 90, it is not a multiple; multiples of a number are obtained by multiplying it by integers, whereas factors divide evenly into the number.
Option C is misleading; 90 has only three distinct prime factors: 2, 3, and 5.
Option D is false because 90 is divisible by both 9 and 18, as 90 divided by 9 equals 10 and divided by 18 equals 5.
