നൽകിയിരിക്കുന്നത്:

A ∶ B = 4 ∶ 5

B ∶ C = 7 ∶ 9

കണക്കുകൂട്ടൽ:

അനുപാതങ്ങൾ താഴെ തന്നിരിക്കുന്നു 

⇒ A ∶ B = 4 ∶ 5

⇒ B ∶ C = [7 × (5/7)] ∶ [9 × (5/7)]

⇒ B ∶ C = 5 ∶ (45/7)

അപ്പോൾ A ∶ B ∶ C എന്ന അനുപാതം 

⇒ A ∶ B ∶ C = 4 ∶ 5 ∶ (45/7)

⇒ A ∶ B ∶ C = 28 ∶ 35 ∶ 45

A B C = 28 35 45

Alternate Method Sunny 28.7.21 

വിപരീത ഗുണന രീതി (ക്രോസ് മൾട്ടിപ്ലിക്കേഷൻ) പ്രയോഗിക്കുമ്പോൾ 

⇒ A ∶ B = (4 ∶ 5) × 7 = 28 ∶ 35

⇒ B ∶ C = (7 ∶ 9) × 5 = 35 ∶ 45

അപ്പോൾ അനുപാതം A ∶ B ∶ C ആണ് 

⇒ A ∶ B ∶ C = 28 ∶ 35 ∶ 45

A B C = 28 35 45
