Question

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.

Answer 1

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
