let the ratio of no.is 7x:5x
now,7x*5x = 2835
45x^2= 2835
x^2= 2835/45
x= √63
x=7.93
putting the value of x
7x= 7*7.93=55.01
5x= 5*7.93=39.05
now,7x*5x = 2835
45x^2= 2835
x^2= 2835/45
x= √63
x=7.93
putting the value of x
7x= 7*7.93=55.01
5x= 5*7.93=39.05

The method was right but there was an multiplication mistake that "7x5 = 35"
