any multiple of 90
The ratio of 18 and 15 is 18:15, but it can be reduced. 3 is the GCF of both numbers, so we can divide each by 3. The ratio of 18:15 after dividing both numbers by 3 is 6:5.
It has been issued in both 15 and 18 certificate cuts.
The lowest common multiple of 15 and 18 is 90
15 and 5 both go into every multiple of 15 .
The LCM of 15 and 18 is 90
Both 15 and 20 can go into 60, as they are both factors of that number.
90 = 15 x 6 = 18 x 5

Both 9 and 3 go into both numbers. 45/54 = 5/6 45/54 = 15/18
You divide each number by a number that can go into both of the numbers evenly. Say a fraction is 15/20, you can divide both numbers by 5. So it would be 3/4. So 15/20 = 3/4. 15/18 divided by 3 you get 5/6 which is the lowest term.
They both go into 90.
