Question

if a/b = 7/3 then find the value of 5a+3b/5a-3b

Answer 1

Step-by-step explanation:

a/b= 7/3 or 7:3. a= 7 , b= 3

5a+3b/5a-3b

= (5×7)+(3×3)/(5×7)-(3×3)

= 35+9/35-9

=44/26

=44/26

= 22/13

hope you got the answer!!

Answer 2

Step-by-step explanation:

if a/b=7/3 then we can assume that a=7k and b=3k,where k is non-zero real number.

now,5a+3b=5*7k+3*3k=35k+9k=44k and

5a-3b=5*7k-3*3k=35k-9k=26k

so,5a+3b/5a-3b=44k/26k=22/13
