Question

Mr Jacques wrote a bonus problem on the board. I f Gina correctly answer, she gets extra time to read. The problem is to write a statement that correctly relates the numbers 9 and 18. Which should Gina write?

a) 18 is a common multiple of 9
and 18
b) 27 is a common multiple of 9 and 18
c) 9 is a multiple of 18
d)18 is a factor of 9

Answer 1

The answer would be A.
B is wrong because 27 is not a multiple of 18
C is wrong because 9 is not a multiple of 18- multiples are higher than the numbers.
D is wrong because 18 is not a factor of 9. factors are what can go into the number, so they will always be smaller than the actual number.
