Answer 1

MARK AS BRAINLIEST
let the no. be 5x and 7x then
according to question, 5 x + 7 x = 720
12x=720
x= 720/12
= 60


first number = 5x = 5×60 = 300
second no. = 7x = 7×60 = 420

Answer 2

5:7

let the numbers are 5x and 7x

so their sum, 5x + 7x = 720

12x = 720

x = 60

so the numbers are 5x60 = 300, and 7x60 = 420
