If our original 3-cup mixture is 3/5 milk, that means that there are $\"+%283%2F5%29%2A3=1.8\"$ cups of milk. Once we add 1 cup of milk, we'll have 2.8 cups of milk in the 4 cup mixture. To turn that into a percent, we'll first divide what we're talking about by the total: $\"+2.8%2F4=0.7+\"$ Multiply that decimal by 100, and you get 70%. \n" ); document.write( "
