Question: If M:N=9:6, then what is the value of (M+N):(M-N)?
- 5:2
- 5:4
- 5:1
- 1:5
Answer: 3. 5:1
Solution:
(M+N):(M-N)
Dividing it by N on denominator as well as numerator
M/N=x=9:6=3:2
(M+N):(M-N)=(x+1)/(x-1)=2.5/.5=5
5:1
Answer: 3. 5:1
Solution:
(M+N):(M-N)
Dividing it by N on denominator as well as numerator
M/N=x=9:6=3:2
(M+N):(M-N)=(x+1)/(x-1)=2.5/.5=5
