Question

divide 45 rupees in ratio of 3:5:7​

Answer 1

we have to divide 45 in 3:5:7

so

3x+5x+7x = 45

15x = 45

x = 3

So for x = 3

3x = 9

5x = 15

7x = 21

so we divide 45 in 3:5:7 by rupees 9, 15, 21.

Answer 2

3x+5x+7x=45

15x = 45
x= 45/15
x=3


3:5:7

3x= 3*3
= 9


5x= 5*3
= 15

7x= 7*3
