Question

What should be added to each term of the ratio 7: 13 so that the ratio becomes 2: 3?​

Answer 1

Answer:

let x is added to each terms of the ratio 7 : 13

so,

(7+x) : (13+x) = 2 : 3

=> (7+x)/(13+x)= 2/3

=> 3(7+x)=2(13+x)

=> 21+3x=26+2x

=> 3x-2x=26-21

=> x=5

so,5 is added to each term of the ratio

Answer 2

Step-by-step explanation:

let the number be x

then according to question

7 + x/ 13 + x = 2/3

3( 7 + x ) = 2( 13 + x )

21 + 3x = 26 + 2x

3x - 2x = 26 - 21

x = 5

therefore the required number = 5
