WebJan 25, 2024 · Answer: Let the fourth proportional to the numbers 4, 9, and 12 be x. Then from the definition of the fourth proportional, we must have: 4: 9 :: 12 : x or in terms of the fractions we can write; 4x = 9 × 12. In other words, we have x = {9 × 12}/4 = 27. Thus the correct option is D) 27. Example 2: The third proportional to 16 and 36 will be:
Web(ii) x, 4, 15 and 30 The given proportion can be calculated for the value of x as follows: x: 4: 15: 30 ⇒ x × 30 = 4 × 15 ⇒ x = (4 × 15) / 30 ⇒ x = 60 / 30 ⇒ x = 2 Therefore the value of x is 2 (iii) 2, x, 10 and 25 The given proportion can be calculated for the value of x as follows: 2: x: 10: 25 ⇒ x × 10 = 2 × 25 ⇒ x = (2 × 25) / 10 ⇒ x = 50 / 10 WebThis is a proportion because 10 is two thirds of 15, just as 2 is two thirds of 3.
