Question

Second term of the proportion whose first, third and fourth terms are 3, 8 and 24
​

Answer 1

Answer:

Let the second term = x

9 : x : : 8 : 24

=> x x 8 = 24 x 9

x = \frac { 24\times 9 }{ 8 } = 3 x 9 = 27

The second term of proportion = 27

Answer 2

9

Step-by-step explanation:

let first discuss that what is meant by proportion

the numbers a,b,c,d

if....a÷b=c÷d

then the numbers a,b,c,d are in

proportion

let the second term be 'a'

means series is...

3,a,8,24

this are in proportion

so...

as per definition of proportion

3÷a=8÷24

then..

by cross multiplication

3×24=8×a

72=8a

a=72÷8

a=9

therefore..

the second number is 9
