Answer: 16, 3.125
Step-by-step explanation:
Okay so lets first look at all the information given to us.
The ratio of water to oats is 16:5
Lin decides to cook 5 cups of oats, and the questions asks how many cups of water should she boil.
So according to the ratio, 5 cups of oats will need 16 cups of water.
The second part asks for the amount of oats needed for 10 cups of water.
so water is 16/5 times the amounts of water. Or basically for x amount of oats, there will be 16/5 amount of water. so we can do 10 = 16x/5
x = 50/16 = 25/8 or 3.125
