Cross-multiplication is a game changer for understanding ratios and proportions in Year 10. Here’s why it’s so helpful:
Simplicity:
It makes tricky fractions much easier.
For example, if you have ( \frac{a}{b} = \frac{c}{d} ), you can cross-multiply to turn it into:
( a \cdot d = b \cdot c ).
Efficiency:
It’s a fast way to find missing values.
You won’t need to worry about hard calculations!
Visual Aid:
It helps you see how numbers are related.
This makes it easier to understand.
Overall, cross-multiplication is a super useful tool that helps you solve proportion problems with confidence!
