Step-by-step explanation:
What Are Ratios?
A ratio is a mathematical term used to describe how much of one thing there is in comparison to another thing.
Ratios are usually written in the following formats:
2:1
2 to 1
2/1
Used in mathematics and everyday life, you may have come across ratios without knowing it – for example in scale drawings or models, in baking and cooking, and even when converting currency for a holiday abroad.
Ratios are useful when you need to know how much of one thing there needs to be in comparison with another thing.
Example 1:
In a bag of 20 sweets, the ratio of blue to pink might be 2:3
The use of ratio in this example will inform us that there would be 8 blue sweets and 12 pink sweets. (This question and the way to work it out is detailed below).
Example 2:
If you are making a cake, and you require 3 cups of flour and 2 cups of sugar to make enough to feed 10 people, then you can express that as the ratio 3:2.
To scale the ingredients up to feed 20 people (to double the recipe size) you need to double the ingredients – so you would need 6 cups of flour and 4 of sugar (or 6:4).
