When you're shopping, using ratios can really help you save money and make better choices. Here’s how to do it:

1. Comparing Prices

Ratios help you compare the prices of different sizes or amounts of products.

For example, let’s say you have two bottles of shampoo.

• The first bottle is 500ml and costs $10.
• The second bottle is 250ml and costs $5.

To find out which is the better deal, you can calculate the price per milliliter using ratios:

• For the first bottle:

  • $10 divided by 500ml equals$0.02 per ml.

• For the second bottle:

  • $5 divided by 250ml also equals$0.02 per ml.

So, both bottles cost the same!

2. Understanding Discounts

Ratios can also help you understand discounts.

Let’s say an item has a discount of 30%.

If the original price is $50, you can easily find out how much the discount is:

• First, calculate the discount amount:

  • $50 times 30$15.

• Now, subtract the discount from the original price:

  • $50 minus$15 gives you $35.

So, the final price is $35 after the discount!

3. Budget Allocation

When you plan your budget for groceries or clothes, ratios can show you how much you should spend on each category.

Let’s say you want to spend 50% of your budget on groceries and 30% on clothes.

If you have $200, you can figure out how much to spend on each:

• For groceries:

  • $200 times 50$100.

• For clothing:

  • $200 times 30$60.

By using ratios like this, you can shop smarter, save money, and stay within your budget!
