Question

*If a+b / a-b = 4/3 then a/b = ?*

1️⃣ 7
2️⃣ 6
3️⃣ -7
4️⃣ 4​

Answer 1

Answer:

We can use componendo-dividendo here.

Step-by-step explanation:

a+b/a-b = 4/3

thus

a/b = 2a/2b = 7

Here what we did is

we first added denominator from numerator on both sides to get a= 7 in numerator and then we substracted denominator from numerator on both side to get b= 1 in denominatior...

thus a/b = 7
