Proportions are really important in Year 10 Maths for a few key reasons:
What Are Proportions?
A proportion shows how two ratios relate to each other. For example, if there are 2 boys for every 3 girls in a class, we can show this as the proportion (2/3).
Cross-Multiplication:
We use cross-multiplication to check if proportions are equal. If we have (a/b = c/d), then we can say (a \cdot d = b \cdot c). This helps us solve real-life problems and makes sure the proportions stay the same.
Where We Use Proportions:
Proportions are helpful in many areas like cooking, reading maps, and managing money. For example, if a recipe needs 4 cups of flour to make 2 loaves of bread, we can find out how much flour we need for 5 loaves by setting up a proportion, like this: (4/2 = x/5).
Comparing Ratios:
Knowing about proportions lets us compare different ratios. This makes it easier to simplify problems and is really important for students getting ready for their GCSE tests.
