Three even numbers sum up to 252. the smallest is half the largest and the middle number is 3/4 the largest. what are the three numbers? enter as a comma separated list.

Let the largest number be x:

smallest number=1/2x

middle number=3/4x

total sum of the numbers is:

x+1/2x+3/4x=252

9/4x=252

solving for x we get

x=252*4/9

x=112

thus the largest number is 112

middle number=3/4*112=84

smallest number=1/2*112=56

Answer: 56,84,112
