a rational is a number that

a rational is a number that can be written as a simple fraction.  For example: 9 can be written as 9/1 and .25 can be writen as 1/4.

An irraional number is a number that CANNOT be written as a simple fraction, like pi or e.  Also many square roots of non-perfect squares are irrational, like the square root of 3.

Help with maths

You may need to talk this through with a teacher, or go to revision sessions after school if you're not comfortable with some of these maths questions.

You could also look through maths revision books if you are concerned with anything.

Try: 

Past questions and exam papers.

Hope this will help!angel
