Answer 2

Yes, they are in proportion

If 9,12,18,24 are to be in proportion , then,

9/12 must be equal to 18/24

9/12 = 18/24

Divide numerator and denominator of LHS [9/12] by 3

9/12 = 3/4 ...(i)

Now, divide the numerator and denominator of RHS [18/24] by 6

18/24 = 3/4 ...(ii)

Comparing (i) & (ii)

Both are equal. Hence 9,12,18,24 are in proportion.

Alternatively

a,b,c,d are in proportion then, a/b = c/d.... ac = bd

A.T.Q: 9/12 = 18/24.... 9*24 = 12*18

216 = 216... LHS & RHS are equal.

Hence they are in proportion
