+4473 Ok, let's compare ratios:
Mixture A - 3:5
Mixture B - 4:7
3/5 = 0.6
4/7 = 0.571
Mixture A is stronger.
Another way to think about it is, you're adding 3 parts concentrate to 5 parts water so think of it as 2 extra parts of water for mixture A.
For mixture B, you are adding 7 - 4 = 3 extra parts of water.
