* 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.*

Ratios are mathematical expressions that compare two or more numbers.

You multiply this number by each of the numbers of the ratio: 35 x 2 = 70, and 35 x 3 = 105. Both numbers added give you the total of 175 dollars.

3 - Scaling ratios By multiplying and dividing, you can use ratios to scale various objects.

For example: The height to width ratio of a piece of fabric is 2:3.

The mathematical term 'ratio' defines the relationship between two numbers of the same kind.

The relationship between these numbers is expressed in the form "a to b" or more commonly in the form: a : b A ratio is used to represent how much of one object or value there is in relation to another object or value.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.Furthermore, when tackling ratio problems, it is always useful to write down all of your working out and double check your answers.Add up the values you have calculated for the ratio parts and if they make the original total value outlined in the question, then you will know you have answered the question correctly.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.(a) - For the ratio , you can make the left-hand side of the ratio equal to 1 by dividing both sides of the ratio by 4: = 4/4 : 20/4 = 1:5 Therefore, the ratio can be written in the form 1:5 (b) - For the ratio , you can make the right-hand side of the ratio equal to 1 by dividing both sides of the ratio by 20: 4: 20 = 4/20 : 20/20 = 0.2:1 Therefore, the ratio can be written in the form 0.2:1 Although ratio problems may appear complex at first, with practice you will find that they are relatively simple to solve.When tackling ratio problems, it is advisable that you revise the main principles of 'Arithmetic with Fractions'.You can calculate equivalent ratios by multiplying or dividing both sides by the same number.In this way, ratios are very similar to fractions: (a) - The ratio of boys to girls is The highest common factor of 21 and 18 is 3 If you divide both sides by 3, the equivalent ratio is 7: 6 Therefore, the simplest form of this ratio is 7:6, meaning that there are 7 boys in the classroom for every 6 girls.
