What is the third proportional of 10 and 30?
Similarly, for 10 and 30 the third proportional is 90.
What is the 3rd proportional?
The third proportional of a proportion is the second term of the mean terms. For example, if we have a:b = c:d, then the term ‘c’ is the third proportional to ‘a’ and ‘b’.
What is the 3rd proportional to 15 and 30?
Therefore, the third proportional to 15 and 30 is 60.
What is third proportional and mean proportional?
If y is the mean proportional of x and z, y^2 = xz, i.e., y = +√xz. For example, the mean proportion of 4 and 16 = +√4×16 = +√64 = 8. If x, y and z are in continued proportion then z is called the third proportional. For example, the third proportional of 4, 8 is 16.
What is the third proportional of 12 and 18?

Hence, the third proportional of 6 and 12 is 24.
What is the third proportional to 12 and 18?
3. 6.
What is the third proportion of 12 and 6?
What is the third proportional of 3 and 27?
Hence, the third proportional of 3 and 27 is “243”.
How do you find the third proportional?
We can write it as a:b = c:d. The quantity c is known as third proportional to the quantities a, b, and d. For example, if we write the quantities 7,8,9, and 10 in the proportional form 7:8 :: 9:10, then 9 is the third proportional to 7, 8, and 10.
What is the mean proportional of 3 and 12?
Answer Expert Verified The mean proportion between 12 and 3 is 6. Therefore the mean proportion between 12 and 3 is 6.
What is the ratio of third proportional to 12 and 30?
Let the third proportional to 12 and 30 be x. = 75. Third proportional to 12 and 30 = 75. = 15. Required ratio = 75 : 15 = 5 : 1. (Note: If you cannot read the numbers in the above image, reload the page to generate a new one.)
Which is the correct answer for the fourth proportional?
Answer: Let the fourth proportional to the numbers 4, 9, and 12 be x. Then from the definition of the fourth proportional, we must have: 4x = 9 × 12. In other words, we have x = {9 × 12}/4 = 27. Thus the correct option is D) 27.
How to find third proportion to 5 and 25?
Find the third proportion to 5 and 25? To find third proportional of any two numbers let say a and b be two numbers and c is in third proportion with a and b
Which is an example of a mean proportional?
The mean proportional between the two terms of a ratio in a proportional is the square root of the product of these two. For example, in the proportion a:b :: c:d, we can define the mean proportional for the ratio a:b as the square root of the product of the two terms of the ratio or √ab.
