Question

If a/b = 2/3 then find the value of the ratio 5a+2b/5a-2b

Answer 1

Answer:

5a+3b/5a-3b. = 22 : 13.

Step-by-step explanation:

a/b = 7/3. ....... Given

a/b×5/3 =7/3 × 5/3. ........... Multiplying both the sides by 5/3

5a/3b = 35/9.

5a+3b/5a-3b = 35+9/35-9....... by componendo-dividendo

5a+3b/5a-3b = 44/26

5a+3b/5a-3b = 22/13

Answer 2

Answer:

5a+2b/5a-2b = 4 : 1

Step-by-step explanation:

It is given that a/b = 2/3

We have to find the ratio of 5a+2b/5a-2b

a/b = 2/3

a = (2/3) × b

Put this value of a in 5a+2b/5a-2b, we get

5a+2b/5a-2b = { [5 × (2/3) × b] + 2b} / { [5 × (2/3) × b] - 2b}

= { [(10/3) × b] + 2b} / { [(10/3) × b] - 2b}

= (10b + 6b) / (10b - 6b)

= 16b / 4b = 4 / 1

∴ 5a+2b/5a-2b = 4 : 1
