a : b = 7 : 9
b : c = 15 : 7
கணக்கீடு:
a : b = 7 : 9 ..................(1)
b : c = 15 : 7 ..................(2)
இரு சமன்பாடுகளிலும் b பொதுவாக உள்ளது, எனவே b ஐ சமமாக்க,
சமன்பாடு (1) ஐ 15 ஆலும், சமன்பாடு (2) ஐ 9 ஆலும் பெருக்க, நமக்குக் கிடைப்பது
a : b = ( 7 x 15) : ( 9 x 15)
b : c = ( 15 x 9 ) : ( 7 x 9)
⇒ a : b = 105 : 135
⇒ b : c = 135 : 63
எனவே, a : b : c = 105 : 135 : 63 = 35 : 45 : 21
எனவே, a : b : c என்பது 35 : 45 : 21.
