Question

The second third and fourth terms of a proportion are 35, 48 and 60 respectively. Find the first term.​

Answer 1

Answer: the first term is 28

Step-by-step explanation:

Let the first term be X

X : 35 = 48 : 60

=> X / 35 = 48 / 60

=> X = (35 * 48) / 60

=> X = 28

Answer 2

Answer:

x=28

Step-by-step explanation:

x : 35 : : 48 : 60

Product of extremes = 60× X = 60x

Product of means = 35× 48 = 1680

A/Q

60x = 1680

x = 1680/60 [ cut both the ziro]

x = 28

Thus , 28 : 35 : : 48 : 60 ans
