Rate, ratio, and proportion are used in many everyday situations, even if we don’t always notice them.
Rate is used when comparing two different quantities. For example, speed is a rate (kilometres per hour), salary per day, or the cost of fuel per litre.
Ratio compares two quantities of the same kind. Common examples include mixing juice in a ratio of 1:4 (juice to water), comparing boys to girls in a class, or ingredients used in cooking.
Proportion shows that two ratios are equal. For instance, if 2 notebooks cost the same as 4 pencils, or when a recipe is doubled and ingredients are increased in the same ratio.
These simple concepts become much easier to understand with clear explanations and practice, which is exactly how Sorry Teacher helps students learn maths step by step.

Ratio
A proportion is a statement that says "These two ratios are equal".
Proportional reasoning relies on ratios. A key idea is that every ratio can be written as a fraction, and every fraction can be thought of as a ratio. Example: I make just 2/3 as much as my husband – this is thinking about it as a fraction.
A large proportion of my daily activities are spent in school.

Rates are ratios ... Speed is a rate of distance per unit of time... ratio of distance to time. Proportions are two equal ratios, whether they are rates or not.
