Please explain how you do ratios
A ratio can be simplified by dividing both sides of the ratio by the Highest Common Factor (HCF). The highest common factor is the largest number that goes into both numbers of your ratio. In example 1 you are asked to simplify the ratio 6:8. Here the HCF is 2 so divide both sides of the ratio by 2 to give 3:4.

What is the definition of rational numbers
Any number which can be written as the ratio of 2 integers, eg 22.5 , which can be written as 45/2. Every finite decimal is a rational number. Since in the general ratio p/q, q may equal 1, every integer is a rational number.
Many numbers do not fit this definition, the best known of which is Pi, or maybe SQRT(2).

Trying to solve the area of a triangle
The are of a triangle is 1/2 * the base * the height.
So if the triangle is 2 for the base and 4 for the height. it would be (2*4*1/2) or 2*4=8, 8*1/2=4. So the area of the triangle would be 4 square (until of measure).
Of course this assumes you know the base and the height of the particular triangle.
This site might be a bit more helpful for calculations where some of the numbers may not be known. Good luck!
