Using ratios to solve real-life word problems can be pretty simple when you're in Year 11 Mathematics. Here are some helpful steps to follow:
Identify the Elements: First, read the problem closely to find out what quantities are involved. For example, if a recipe says the ratio of flour to sugar is 3:2, make sure you know what those numbers mean.
Set Up the Ratio: Next, write down a ratio equation based on the information you have. If you have 6 cups of flour, you can figure out how much sugar you need using the ratio:
Flour : Sugar = 3 : 2
To find the sugar, you can use this formula:
Sugar = (6 cups of flour × 2) / 3 = 4 cups of sugar.
Cross-Multiply for Proportions: This step comes in handy when you’re comparing two ratios. For example, if you have the ratio of boys to girls as 4:5 and you want to know the total number of students, you can set up the equation like this:
4x + 5x = Total Students.
By carefully reading the problem and using these steps, you can easily use ratios in real-life situations!
