Question

the sum of numerator and denominator is 3 less than twice numerator and denominator is decreased by 1 then rhe fraction becomes 1/2​

Answer 1

Step-by-step explanation:

•2(N)=N+D+3

°2N-N=D+3

°N=D+3

N/D= 1/2

°D+3/D=1/2

°2(D+3)=D

°2D+6=D

°D=6,N=D+3 =6+3=9

Original ratio :N/D=9/6=3/2
