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

I thought I already answered this, just incase not, it's A because 9x2 is 18 and 18x1 is 18.

20 percentage, you can also do it on a calculator.
