If 20% of a mixture is water and the rest is alcohol, what is the ratio of alcohol to water in the mixture?

If 20% of a mixture is water and the rest is alcohol, what is the ratio of alcohol to water in the mixture?

Step 1: Understand that the mixture is made up of two components: water and alcohol.
Step 2: Note that 20% of the mixture is water.
Step 3: Calculate the percentage of alcohol in the mixture. Since the total must equal 100%, subtract the percentage of water from 100%. So, 100% - 20% = 80%.
Step 4: Now you know that 80% of the mixture is alcohol.
Step 5: To find the ratio of alcohol to water, write it as alcohol:water. This is 80%:20%.
Step 6: Simplify the ratio. Divide both parts of the ratio by 20. So, 80 ÷ 20 = 4 and 20 ÷ 20 = 1.
Step 7: The simplified ratio of alcohol to water is 4:1.
