Ex 12.2, 4 Determine if the following ratios form a proportion. Also, write the middle terms & extreme terms where the ratios form a proportion. (a) 25 cm : 1 m and Rs 40 : Rs 160 1 m = 100 cm Now, 25 cm : 1 m = (25 ππ)/(1 π) = (25 ππ)/(100 ππ) = 25/100 = 1/4 = 1 : 4 Rs 40 : Rs 160 = (π π 40)/(π π 60) = 40/160 = 4/16 = 1/4 = 1 : 4 β΄ 25 cm : 1 m = Rs 40 : Rs 160 So, given ratios are in a proportion Here, Middle terms = 1 m, Rs 40 Extreme terms = 25 cm, Rs 160
