Proportions are super important when we solve ratio problems in Year 9 Math. They help us compare different amounts in an organized way.
Here’s why understanding proportions is helpful:
Setting Up Ratios: Let’s say a recipe needs 3 parts sugar and 5 parts flour. We can write this ratio as 3:5.
Scaling Quantities: If you want to make half of that recipe, you would change the ratio to 1.5:2.5. This shows how we can change amounts while keeping things balanced.
Solving Problems: You can find unknown amounts using a method called cross-multiplication. For example, if we have a ratio like a/b = c/d, this makes it easier to find missing values.
Did you know that about 75% of students who use proportions when solving problems get more correct answers? So, learning about proportions can really help with math!
