Step-by-step explanation:

Let the number be x

-9/25 + x = -21/15

x = 9/25 - 21/15

x = 9×15 - 25×21/25×15

x = 135-525/375

x = -390/375

x=-104/100

let required number be x,

-9/25+x= -21/15

-9+25x/25=-21/15

-9+25x=-21/15 x 25

-9/25x=-35

25x=-35=9

25x=-26

x=-26/25

as we know -21/15=-7/5

and-26/25=-7/5

so both contain same value

if it is helpful than mark me as brainlist
