Year 9 students can improve their math skills by looking at how ratios and fractions are connected. Understanding this relationship makes tough math problems easier, especially those that involve proportions.

What's the Connection?

Ratios compare one part to another part, while fractions show how much of a whole something is. For example, if a recipe needs sugar and flour in a 2:3 ratio, that can also be shown as a fraction. In this case, sugar makes up $\frac{2}{5}$ of the total mix (2 parts sugar out of 5 total parts).

How to Use This

When working on problems with ratios, students can turn ratios into fractions to make calculations easier. For example, if a class has a ratio of boys to girls as 3:2, here's how to figure out the fraction of boys in the class:

$$\text{Fraction of boys} = \frac{3}{3 + 2} = \frac{3}{5}$$

In Summary

By seeing how ratios and fractions are linked, students can make difficult problems simpler. They can also compare things and understand real-life situations better. This knowledge helps build a strong base for solving different math challenges.
