How To Solve Ratios Problems-59
When scaling ratios up or down, always remember that the same unit of measurement must be applied to both sides; i.e. As a result, the piece of fabric must be 120mm wide.4 - Writing a ratio in the form 1:n or n:1 As well as being able to write a ratio in its simplest form, you must also be able to write a ratio in the form: 1:n or n:1 where 'n' can be any whole number, fraction or decimal.For example: If there are 10 apples and 5 oranges in a bowl, then the ratio of apples to oranges would be 10 to 5 or 10:5. In contrast, the ratio of oranges to apples would be 1:2.

The specific questions you will be expected to answer will vary depending upon which examination board with which you are registered, but as a rule you will be required to: 1 - Dividing in a ratio Without realizing, you use ratios every day in order to divide and share out amounts fairly.

As a result, there will be questions within your GCSE maths exam where you will be required to use ratios in order to share out amounts of money or other items: (a) - Firstly, you need to find the total number of parts in the ratio.

This means that, for every 2 units of height, there must be 3 units of width.

Consequently, if the piece of fabric was extended to be 20m high, it must be 30m wide. For example, if the piece fabric was made 80mm high, its width must be of the same unit of measurement and retain the rules of the ratio 2:3.

Otherwise the calculator finds an equivalent ratio by multiplying each of A and B by 2 to create values for C and D. The calculator solves for D = C * (B/A) Enter A, B and D to find C.

The calculator will simplify the ratio A : B if possible.

You can do this by adding up the number values in the ratio to get a total. This means that you need to share the money into 5 equal parts.

Now you need to calculate the amount which one part will receive.

wiki How is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. They can compare absolute quantities and amounts or can be used to compare portions of a larger whole.

To create this article, 49 people, some anonymous, worked to edit and improve it over time. Ratios can be calculated and written in several different ways, but the principles guiding the use of ratios are universal to all.
