You can treat Ratios like coordinates on a graph.

If you have a ratio in its simplified form, like 1 : 4

And then if you scale it up by multiplying - we learnt this is in my previous post on gcse maths ratios.

You can create a set of ratios like this:

Ratio is a level 4/5 topic and, depending on where they decide to throw it in, can easily be a level 6 to 9 topic too.

Ratio can come up in both the foundation and higher gcse maths exam.

Its worth spending time to learn what ratio is and the different kinds of questions that can come up.

The questions on ratio in the foundation paper are usually quite straight forward.

Percent is a big topic in Secondary School Maths. If you don’t fully understand percentages whilst in KS3 - years 7 to 9 - you will struggle a lot in year 10 and 11 whilst preparing for your GCSE maths exam.

By the way, the work you do in years 7, 8 and 9 is the foundation maths GCSE. So, although nobody tells you, you do actually start your maths gcse in year 7.

Oooooh. Algebraic Fractions eh?

You know I love maths, so I could sit and do them all day long...but for most 'normal' people these are a nightmare...and they get worse.

Algebraic fractions are mostly level 7 and upwards, so an easy version could potentially pop up in the foundation paper, but they are usually always in the higher tier GCSE maths exam. Fun times.
