Problem solving with algebraic ratios

In the compound measures unit, pupils will be exploring the multiplicative relationship between different compound measures. Ratio will be one of the ways in which this is explored and the skills from this unit will aid understanding.

The ratio unit will cover comparing fractions, percentages and ratios and being able to move fluently between them. The percentages unit ensured pupils had the opportunity to work with finding the percentage of an amount and the opportunity to calculate interest.

In this unit pupils will learn how to combine ratios, interpret algebraic ratios, and investigate quantity changes and their effect on ratios.

Ratio

A reciprocal is the multiplicative inverse of any non-zero number. Any non-zero number multiplied by its reciprocal is equal to 1

A ratio shows the relative sizes of two or more values and allows you to compare a part with another part in a whole

A ratio shows the relative sizes of 2 or more values and allows you to compare a part with another part in a whole

A part to whole (sometimes part to part) comparison. If two things are proportional then the ratio of part to whole is maintained and the multiplicative relationship between parts is also maintained.

A ratio shows the relative sizes of 2 or more values and allows you to compare a part with another part in a whole.

LCM is an abbreviation for lowest common multiple.

The lowest common multiple is the lowest number that is a multiple of two or more numbers.

A numerical coefficient is a constant multiplier of the variables in a term.

An equation is used to show 2 expressions that are equal to each other.

Proportionality means when variables are in proportion if they have a constant multiplicative relationship.

A ratio shows the relative sizes of two or more values and allows you to compare a part with another part in a whole.

Coordinates are a set of values that show an exact position.

An expression contains one or more terms, where each term is separated by an operator.

The probability that an event will occur is the proportion of times the event is expected to happen in a suitably large experiment.
