Hi guys,

This question has me a bit stumped and I can't seem to find any methods on Google that would help me solve this:

The last part of the question asks me to find the value of the scale factor, which in this equation I believe is 1.8.

I know how to calculate percentage increases the normal way, but I have never come across this sort of questions before, I'm unsure of how I can use the scale factor to calculate the percentage increase of the figures recorded in the table :(

Can anyone give me a hint here? :cool:

Cheers for any help :D

FAQ: Calculate % Increase from Scale Factor: Stumped? Help Here!

What is a scale factor?

A scale factor is a number that represents the size ratio between two similar figures. It is used to scale or resize an object by multiplying the original dimensions by the scale factor.

How do I calculate the scale factor?

The scale factor can be calculated by dividing the new dimension by the original dimension. For example, if the new length is 10cm and the original length is 5cm, the scale factor would be 10/5 = 2.

How do I calculate the % increase from a scale factor?

To calculate the % increase from a scale factor, subtract 1 from the scale factor and then multiply by 100. For example, if the scale factor is 2, the % increase would be (2-1) x 100 = 100%.

What is the difference between a scale factor and a percentage increase?

A scale factor is a numerical value that represents the size ratio between two figures, while a percentage increase is a measure of the change in size expressed as a percentage of the original size. While they may be related, they are not the same thing.

How can I use the % increase from a scale factor in real life?

The % increase from a scale factor can be used in a variety of real-life situations, such as resizing images, calculating sales or population growth, or determining the increase in salary or price over time.
