L14 S1 Ratio Tables

A ratio is a comparison of two quantities that shows the relative size of one quantity to another, often expressed as 'a:b'.

To simplify a ratio, divide both terms by their greatest common factor (GCF).

A ratio table shows pairs of numbers that form equivalent ratios, helping to visualize the relationship between quantities.

$21 (using the ratio 3:9, which simplifies to 1:3, so 7 apps cost 7*3 = $21).

10 weeks to 7 days.

Identify the quantities in the table, then express them as a fraction and simplify if necessary.

5:6 (simplified from 10:12).

It could represent the ratio of girls to boys if there are 2 girls and 5 boys.

Use the unit price from the ratio to multiply by the number of items.

$60 (using the ratio 5:15, which simplifies to 1:3, so 20 bags cost 20*3 = $60).
