They can all be divided by three, which turns 12/15 into 4/5, and 9/12 into 3/4. 4/5 is bigger than 3/4.
12 to 15 is greater than 5 to 9 because the numbers in the former are of higher value than the latter.
9 over 12
3, 6, 9, 12, 15
3, 6, 9, 12, 15
8 is two thirds of 12 so that 8/12 = 2/3. 9 is greater than 8 so 9/12 is greater than 8/12 which is 2/3.
3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
-3
No. 12 millimeters is greater than 9 millimeters just as 12 inches is greater than 9 inches.
3, 6, 9, 12, 15, 18, 21, 24 . . .
3, 6, 9, 12, 15
11/12 is greater than 8/9 8/9 = 11/12 by cross multiplication: 8 * 12 = 9 * 11 96 < 99 thus, 11/12 is greater than 8/9
9/18 = 0.5 8/15 = 0.53 8/15 is greater.
