Question

Jim needs to mix a medication with water to make the appropriate solution. The medications says to mix 3 oz of medication with 5 cups of water. Jim has 23 oz of medication. how much water will he need? solve using proportion ( please step boy step so I can understand this)

Answer 1

Answer:

38 or 38.33 cups of water.

Step-by-step explanation:

You need 5 cups of water for every 3 ounces of medication. We can set up a proportion: #oz of medication/#cups of water= #oz of medication/# cups of water. We can plug in some numbers from the problem.

3/5=23/n. You can use any variable, but I'm using n for how many cups of water Jim will need for 23 ounces of medication.

We can cross multiply: 3*n=5*23.

3n=115

We divide both sides by 3.

n=38.3333333.......

Rounding to the nearest whole number, Jim will need 38 cups of water, or 38.33 cups if you're rounding to the nearest hundredth.

Hope this helps :)
