If The middle number is
2
3
the largest.
mean:
The middle number is 2 / 3 the largest.
then:
a = smalest number
b = middle number
c = largest number
a = c / 2
b = ( 2 / 3 ) c
a + b + c = 104
c / 2 + ( 2 / 3 ) c + c = 104
3 c / 6 + 4 c / 6 + 6 c / 6 = 104
13 c / 6 = 104 Multiply both sides by 6
13 c = 104 * 6
13 c = 624 Divide both sides by 13
c = 624 / 13 = 48
a = c / 2 = 48 / 2 = 24
b = ( 2 / 3 ) c = 2 * 48 / 3 = 96 / 3 = 32
a = 24
b = 32
c = 48
Three even numbers sum up to 104. The smallest is half the largest and the middle number is
2
3
the largest. What are the three numbers?
