Question

if the reciprocal ratio of (2a+b):(a-b) is the ratio (a+2b):(3a-2b) then find the duplicate ratio​

Answer 1

ANSWER:

(1) Duplicate of 9b2:ab is equal to 81b4:a2b2

 The compound of 2a:3b and the duplicate of 9b2:ab is 2a×81b4:3b×a2b2=54b:a

(2) Sub duplicate ratio  of 64:9 is 8:3

The compound of the sub duplicate ratio of 64:9 and the ratio 27:56 is 8×27:3×56=9:7

(3) Duplicate ratio of b2a:b2ca2 is equal to b24a2:b4ca4

The compound of the duplicate of ratio b2a:b2ca2 and the ratio 3ax:2by is
