5/8 is more than 11/20
If we find the lower common multiple of the denominators which is 160 then we can multiply the top numerators by the opposite denominators
5x20=100
11x8=88
We now have
The one on the left is simplified to 5/8 and the right is simplified to 11/20

The coordinates would be multiplied by 3, as the scale factor is 3, and it is a dilation, so we know the size increases.
You divide the top by the battle
