A salt modure has 7 parts water and 1 part salt Suppose another part of salt is added What is the new ratio of salt
Sunny_sXe [5.5K]

Answer:

14:2 - 14 parts water and 2 parts salt

Step-by-step explanation:

The original ratio was 7:1. So, that means if you added another part to the salt it would make 2. That means that the 7 parts of water would become 14 parts. Since the ratio of the salt part was doubled from 1 to 2, you would have to do the same with the water ratio part. Hoped this helped!
