Let the first number be x
so second number is 2x
so third number is 2x/3
so their sum=x+2x+2x/3=11x/3
so their average is 11x/9
so 11x/9=44
or 11x=44×9
or x=(44×9)/11
or x=36
so first number is 36
second number is 36×2=72
third number is 72/3=24
so second number is 2x
so third number is 2x/3
so their sum=x+2x+2x/3=11x/3
so their average is 11x/9
so 11x/9=44
or 11x=44×9
or x=(44×9)/11
or x=36
so first number is 36
second number is 36×2=72
third number is 72/3=24
