Dunno

Answer 2

Answer:4/7

Step-by-step explanation:

Let the required fraction be (N/D), where N&D denotes numerator and denominator respectively.

By question,

D=(N+3)......(1)

(N+2)/(D+5)=1/2........(2)

From (2), 2(N+2)=1(D+5)

Or, 2N+4=D+5

Or, 2N-D-1=0

Or, 2N-(N+3)-1=0. (Using equation 1)

Or, 2N-N-3-1=0

Or, N-4=0

Therefore N=4

Now using this value of N in (1) we get

D=(N+3)=(4+3)=7

Therefore required fraction (N/D) is 4/7
