Answer 1

Answer:

hello mate!

Step-by-step explanation:

question Number 6)

2 numbers,

4 is added to both the numerator and Denominator,

8/3= 8x/3x and

here X is the common factor between those numbers, it was being striked out as a result, it's ratio.

8x/3x. are the 2 numbers

as 4 is added.

8x+4/3x+4= 12/5.

cross multiplication .

5(8x+4)=3x+4(12)

40x+20=36x+48.

Transposing 36 x to R.H.S and 20 to L.H.S,

40x-36x=48-20.

4x=28.

x=7.

hence, The Numbers are

1st number = 8x = 8 ×(7) = 56.

2nd number = 3x = 3×(7)= 21.

Verification:-

56/21=8/3

7×2×2×2/7×3= 2×2×2/3=8/3

8/3=8/3.

56+4/21+4= 60/25= 12×5/5×5= 12/5.

hence, satisfied.

thank you mate!

Have a great day ahead!
