Question

Set up all possible proportions from the numbers 12, 15, 8, and 10?

Answer 1

Answer:

There is only 4 possible proportions

(i) 12 : 15 = 8 : 10   (ii) 15 : 12 = 10 : 8   (iii)12 : 8 = 15 : 10 (iv) 8 : 12 = 10 : 15

Step-by-step explanation:

All the possible proportions are :

1. 12 : 15 = 8 : 10   #(3 × 4 = 12 : 3 × 5 = 15) = (2 × 4 = 8 : 2 × 5 = 10)
2. 15 : 12 = 10 : 8   #(3 × 5 = 15 : 3 × 4 = 12) = (2 × 5 = 10 : 2 × 4 = 8)
3. 12 : 8 = 15 : 10   #(4 × 3 = 12 : 4 × 2 = 8) = (5 × 3 = 15 : 5 × 2 = 10)
4. 8 : 12 = 10 : 15  #(4 × 2 = 8 : 4 × 3 = 12) = (5 × 2 = 10 : 5 × 3 = 15)
