To find important information in ratio word problems, start by highlighting the important numbers and keywords.

Look for words or phrases like "for every," "in the ratio of," or "split into." These words show how different amounts are related to each other.

Here's an example:

• Problem: "A recipe needs sugar and flour in a ratio of 1:3. If you use 2 cups of sugar, how much flour do you need?"

  Key information:

  • Ratio: 1:3
  • Sugar used: 2 cups

Next, change the ratio into a fraction. In this case, the total parts = 1 + 3 = 4.

• Calculate how much flour you need:
  Flour = (3 parts flour / 1 part sugar) × 2 cups of sugar = 6 cups of flour

By using this simple approach, you can easily solve ratio problems!
