When preparing for the HESI A2 entrance exam, the math section can give you a run for your money—especially when it comes to solving ratios. Whether you’re planning to become a nurse or another type of healthcare professional, you need to know how to work with ratios. The good news is that once you understand the basics, it’s not as intimidating as it seems. Let’s dive into what you need to know about solving ratios on the HESI A2 math section.
What Are Ratios and Why Are They Important?
A ratio is a comparison between two or more numbers, showing the relationship between them. Think of it like a recipe—if it calls for 2 cups of sugar and 1 cup of water, the ratio is 2:1. Ratios are crucial in healthcare, where you often need to calculate dosages or proportions. On the HESI A2 math section, you can expect to see several questions involving ratios, so let’s make sure you’re ready for them.
Common Ratio Questions on the HESI A2 Math Section
Ratios can pop up in various forms on the HESI A2 math section. Here’s what you might encounter:
- Simple Ratios: Basic comparisons between two quantities, like the sugar-to-water example. You might need to find the ratio or use it to determine a missing value.
- Proportions: A proportion is two ratios set equal to each other. You might need to solve for an unknown in a proportion, like when you’re adjusting a recipe for a larger batch.
- Rates and Unit Rates: This involves comparing different units, like miles per hour or dollars per ounce. You might need to find the rate or convert between units.
Tips for Solving Ratios on the HESI A2 Math Section
If ratios have you scratching your head, don’t worry. Here are some tips to help you get the hang of them:
1. Understand the Basics
Start by getting a solid grasp of what ratios represent. They can be written in different ways, like 2:1, 2/1, or “2 to 1.” Know that the order matters—2:1 is not the same as 1:2. Once you’re clear on this, the rest gets easier.
2. Work with Proportions
Proportions are powerful for solving ratio problems. If you have two ratios set equal to each other, you can cross-multiply to solve for an unknown. For example, if 3x=26, you can cross-multiply to get 2x=18, leading to x=9.
3. Convert Units When Needed
Ratios often involve different units, like in rates. Be ready to convert between units to find the correct ratio. If you’re dealing with rates, like miles per hour, understand how to break them down to find the unit rate.
4. Use Scratch Paper/White Board (if your test center allows)
When solving ratio problems, scratch paper/white board is your best friend. Use it to write out the ratios, cross-multiply, and do any calculations. This helps you keep track of your work and spot errors before submitting your answer.
5. Practice, Practice, Practice
The best way to get comfortable with ratios is to practice. Work through a variety of ratio problems to get a feel for the different types you might encounter on the HESI A2 math section. Our HESI A2 math study guide is packed with practice questions to help you build your skills.
