Sagot :

Proportion: 2:5:7 = 72:180:252

Solution:
2+5+7 = 14
Let x be the 1st number, y be the 2nd number and z be the 3rd number

X = 2/14
Y = 5/14
Z = 7/14

The sum of x, y, and z is 504 so to get each number

2/14 of 504 is x
504(2/14) = 72

5/14 of 504 is y
504(5/14) = 180

7/14 of 504 is z
504(7/14) = 252

Answer: The three numbers are 72, 180, and 252
