Verified answer

Example : the five positive numbers are a, b, c, d, and e,, the sum = x

a + e = 15
b = 1/3 x
c = 1/4 x
d = 1/5 x
otomatis a = 1/2 x dan e = 1/6 x

1/2 x + 1/6 x = 4/6 x = 2/3 x
a + e = 15
2/3 x = 15
x = 15 : 2/3
= 45/2

the value of the largest number is
a = 1/2 x = 1/2 ( 45/2 ) = 45
=>> 45

maaf kl salah
