Question

Determime if the fallowing ratio from the proportion also write the middle term and extreme terms where a ratio from a propertion 25cm:1m and $ 40 : $ 160

Answer 1

Here, 25 cm : 1 m = 25 cm : 1 ×100 cm                 [∵1 m = 100 cm] =25:100=25100=25÷25100÷25=14=1:4[dividing numerator and denominator both by 25] and Rs. 40 : Rs. 160 = 40 : 160 =40160=416=14=1:4[dividing numerator and denominator both by 10] Here, 1 : 4 = 1 : 4 i.e. 25 cm : 1 m = Rs. 40 : Rs. 160 So, the ratios of 25 cm : 1 m and Rs. 40 : Rs. 160 are in proportion. i.e. 25 cm : 1 m :: Rs. 40 : Rs. 160 Now, middle terms are 1 m and Rs. 40 and extreme terms are 25 cm and Rs. 160.
