Question

determine the numbers 12,18,28,and 50 are in proportion

Answer 1

Answer:

12:18::28:50

a:b::c:d

so,a*d=b*c        a=12 b=18 c=28 d=50

12*50=18*28

600=504

here L.H.S is not equal to R.H.S

Step-by-step explanation:

Answer 2

Answer :

No, the numbers are not in proportion.

Step-by-step explanation :

A group of numbers is said to be in proportion if the product of their extremes is equal to product of their means.

Here,

12, 18, 28, 50

Extremes = 12 and 50

Product if extremes = 12 * 50 = 600

Means = 18 and 28

Product of means = 18 * 28 = 504

So, we conclude that ;

600 ≠ 504

∴ Product of extremes ≠ Product of means.

Hence, the given set of numbers are not in proportion.
