Question

the ratio of the three numbers is 5:6:7. if the sum of those three numbers is 54, Find those numbers?​

Answer 1

Answer:

Ratio of three numbers = 5x: 6x: 7x

7x + 5x = 6x + 48

12x = 6x + 48

6x = 48

x=8

The numbers are 5(8) = 40, 6(8) = 48

and 7(8) = 56

So, The third or middle number is 48.

Answer 2

5x+6x+7x= 54

18x=54

x=54/18

x=3

5x=5×3=15

6x=6×3=18

7x=7×3=21
