25/4 = n/12
The means are 4n
The extremes are25(12)
4n = 25(12)
4n = 300
4n / 4 = 300 / 4
n = 300/4
n = 75

Cross-multiply:
4*n=12*25
4n=300
4/4n=300/4
n=75
Check:
25/4=75/12
25/4=25/4

25/4=n/12
. . . ,----------,
=> 25:4=n:12
. . . . . '---'
=> 25*12=n*4 (By cross multiplication)
=> n=25*12/4
=> n=25*3
=> n=75

12 x 25 = 4n
4n = 300
n = 75

25/4 = n/12
4 * n = 25 * 12 ---- By cross-multiply
4n = 300
n = 300/4
n = 75

Multiply both sides by 12, and you have
(25/4)*12 = (n/12)*12
25*3 = n
n = 75

well first you want the numerators to be equal, so multiply both sides by 25, then you'll have 25/4 = 25/12, since the denominators are equal thats your answer.

n/12 = 25/4
n = (25/4) x 12
n = 75
