Question

if a/3=b/5then (a+3):(b+5) ?

Answer 1

Answer:

3/5

Step-by-step explanation:

=> a/3 = b/5

Add 1 to both sides,

=> (a/3) + 1 = (b/5) + 1

=> (a + 3)/3 = (b + 5)/5

=> (a + 3)/(b + 5) = 3/5

An another method to solve:

a/3 = b/5 , as we know 1 = 1,

So, we can say a/3 = b/5 = 1.

a = 3 & b = 5

Therefore,

=> (a + 3)/(b + 5) = (3 + 3)/(5 + 5)

=> 6/10

=> 3/5

Answer 2

Step-by-step explanation:

a/3 =b/5

5 a=3b

a=3b/5

then

a+3/b+5

put the value of A

3 b/5+3/b+5

3b+15/b+5

3 combine

3 (b+5) / (b+5)

then cut (b+ 5)

(a+3): (b+5)=3:1
