SolutionPutting a = 4q and b = 3q in a * b = (3a 2b)/(3a Ã¢Â€Â“ 2b).(4q * 3q) = [3(4q) 2(3q)]/ [3(4q) - 2(3q)]= (12q 6q) / (12q Ã¢Â€Â“ 6q)= 18q/6q = 3So, 5p * (4q * 3q) = 5p * 3Put p= 1/5 in 5p * 3we get 5 x 1/5 * 3 = 1 * 3= [3(1) 2(3)]/ =[3(1) - 2(3)]= (3 6)/(3 Ã¢Â€Â“ 6)= 9/-3 = - 3Answer-(C) - 3

What happened to q=3 they didnÃ¢Â€Â™t do anything with that. They should have multiplied 4q and 3q by 3 before solving the question.

## Ans 7:

Class : Class 8
please explain someone why to put a=3q and b=4q

Class : Class 4
Putting a = 4q and b = 3q in a * b = (3a 2b)/(3a Ã¢Â€Â“ 2b). (4q * 3q) = [3(4q) 2(3q)]/ [3(4q) - 2(3q)] = (12q 6q) / (12q Ã¢Â€Â“ 6q) = 18q/6q = 3 So, 5p * (4q * 3q) = 5p * 3 Put p= 1/5 in 5p * 3 we get 5 x 1/5 * 3 = 1 * 3 = [3(1) 2(3)]/ =[3(1) - 2(3)] = (3 6)/(3 Ã¢Â€Â“ 6) = 9/-3 = - 3 Answer-(C) - 3
