9 to 12 is the ratio. BUT, if you simplify it (divide them both by the same number which makes both of them come out to a whole number)
it's 3 to 4
7*n-n 7*2-2=12 9*2-2=16
9/12 = 3/4
3:4
It is: 3 to 4
6/12
9 x 12 = 81 9/12 = 3/4 = 0.75
12/27, which can be simplified to 4/9
It is: 3 to 4
3 to 4
4 to 3
It is: 2 to 9
9 to 12 = 3 to 4 in its lowest terms
