Question

Check whether 8, 9, 24, and 27 are in proportion.​

Answer 1

Answer:

8, 9, 24, and 27 are in proportion.​

Step-by-step explanation:

To check whether 4 given numbers are in proportion, arrange them in proportion and check the product of their means and the product of their extremes.

If they both are equal, then the given numbers are in proportion.

First, lets arrange 8, 9, 24, and 27 in proportion.

8 : 9 = 24 : 27

Now, the means of this proportion have been made in bold and the extremes have been made in italics.

Now,

Product of means = 9 × 24

                              = 216

Product of extremes = 8 × 27

                                  = 216

Since Product of means = Product of extremes, the numbers are in proportion.
