The given ratio is 16:12
WE can get other raios that are the same by dividing the ratio by common factors till the lowest terms are derived or by multiplying by constant terms too.
Dividing by 2, it becomes 8 : 6
Dividing further by 2, it becomes 4: 3
This is the lowest
If we multipy by 2,the ratio would be 32:24
If we multiply by 2 again, the ratio would be 64:48
If we multiply by 3, the ratio would be 48:36
The answers are 32:24, 48:36 and 64:48
