    let, x must be added.

    Now, (7+x)/(13+x) = 2/3

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

    or, 21+3x = 26+2x

    or, 3x-2x = 26-21

    or, x = 5.

    so, 5 must be added.

    Answer:

    pls mark as brainliest

    Step-by-step explanation:

    solution :

    given ratio = 7:13

    Let x should be added to each term so it become 2:3

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

    – 3(7+x) = 2( 13 + x)

    = 21 + 3x = 26 + 2x

    – 3x – 2x = 26 – 21

    » x= 5

    .: We should add 5 to each term of the ratio to 7:13 so it becomes 2:3
