How do you find the continued proportion?

Two ratios a: b and b: c is said to be in continued proportion if a: b = b: c. In this case, the term c is called the third proportion of a and b whereas b is called the mean proportion of between the terms a and c. Find out if the following ratios are in proportion: 8:10 and 12:15.

How do you know if a number is in proportion?

Approach: If four numbers a, b, c and d are in proportion then a:b = c:d. The solution is to sort the four numbers and pair up the first 2 together and the last 2 together and check their ratios this is because, in order for them to be in proportion, the product of means has to be equal to the product of extremes.

What is fourth proportion?

If a:b :: c:d or in other words a:b = c: d, then the quantity 'd' is what we call the fourth proportional to a, b and c. For example, if we have 2, 3 and 4, 5 are in the proportion such that 2 and 5 are the extremes, then 5 is the fourth proportional to 2, 3, and 4.

What are the second and third terms of a proportion?

The first and fourth terms are called the extremes of the proportion. The second and third terms are called the means of the proportion. the terms a and d are the extremes; the terms b and c are the means.
