Percentages are not just something we study at school or teach during our tuition lessons, percentages are something that everyone uses on weekly basis. Whether it is looking at a credit card APR, sorting out a mortgage or looking at the sale items in a shop, percentages are everywhere and it is really useful to know how they work and what different types there are. 

What is percentage change and how do I calculate it? 

Percentage change is the amount a number goes up or down as a percentage to the original amount so if 50 goes up to 75 then this is a 50% increase. This can be calculated by dividing the change 25 in this case, the original which is 50 then multiply by 100. 

How to calculate a percentage of something?

You can convert the percentage to a decimal and multiply. So 25% of 80, is 0.25 x 80 = 20. 

Calculating a percentage?

Ben gets 20 out of 50 in a maths test, what percentage is this? Amount/Total x 100, so 40% in this example.

Percentages are also a really important part of the GCSE syllabus. Our maths tutors in Knaresborough understand the importance of relating topics in maths to real life situations like the interest a bank pays or how much money you save when there is a 20% discount applied. as children and people generally relate to this better.
