This is the third in our Easy section of Eleven Plus maths quizzes on Multiples. In it we shall ask you to find common multiples, and odd men out, as well as giving you some tips to help you in your exams. We’ll also be looking at multiples of fractions and decimal numbers.
That’s right – fractions and decimals do have multiples, which seems odd given that whole numbers cannot have fractions as their multiples. It’s all to do with whether or not a number can be divided by another without leaving a remainder. So, 21⁄2 is a multiple of 1⁄2 because 5 x 1⁄2 = 21⁄2. However, 21⁄2 is NOT a multiple of 5. That’s because 5 x 0.5 = 21⁄2 and 0.5 is not a whole number.
Okay, now we’ve cleared that up, it’s time for the quiz. Read all the questions carefully – there are some crafty onesto fool the careless. Don't let them fool you!
