To Find :

⬤ The Numbers are in Proportion or Not .

Solution :

As we know , Product of Extremes = Product of Means . Hence ,

Now :

35 : 7 :: 60 : 12

Product of Extremes = 35 × 12

Product of Means = 7 × 60

Product of Extremes = Product of Means

(35 × 12) = (7 × 60)

$\bf{420 = 420}$

As we can see that , Both are Equal .

Therefore , 35 , 7 , 60 and 12 are in Proportion .
