Worked practice questions

For two positive integers a and b, HCF(a, b) x LCM(a, b) equals:

  1. a x b
  2. a + b
  3. a - b
  4. a / b
Show answer and solution

Correct answer: A. a x b

1. Check with 6 and 20: 2 times 60 is 120. 2. That equals 6 times 20. 3. Use it to find LCM once HCF is known. _Source: syllabus Mathematics, Chapter 1, Real Numbers._

LCM(6, 72, 120) is:

  1. 216
  2. 360
  3. 720
  4. 120
Show answer and solution

Correct answer: B. 360

1. Greatest powers are 2 cubed, 3 squared and 5. 2. 8 x 9 x 5 is 360. 3. The HCF is 6. _Source: syllabus Mathematics, Chapter 1, Real Numbers._

A number that cannot be written as p/q with integers p and q (q not zero) is:

  1. Composite
  2. Integer
  3. Irrational
  4. Rational
Show answer and solution

Correct answer: C. Irrational

1. Root 2 and root 3 are examples. 2. Such numbers are irrational. 3. Together with rationals they make the reals. _Source: syllabus Mathematics, Chapter 1, Real Numbers._
