Question

ex 2 va rog plizzzzzzzzz

Answer 1

a/2 = b/5 = c/8 = d/25
(a+b+c+d)/(2+5+8+25) = 1000/40 = 25
a/2 = 25 
a= 50 m
b/5 = 25  
b=250 m
c/8 = 25   
c=200 m
d/25 = 25
d=625 m

Answer 2

{a ,b , c ,d } d .p { 2, 5 ,8 ,25 }
a +b+c+d = 1000
a/2=b/5=c/8=d/25 = K
a = 2k
b =5k
c=8k
d = 25 K
2k+ 5k+8k+25 K = 1000
40k = 1000
k= 1000:40
k=25
a=2*25
a=50
b = 5*25
b=125
c= 8*25
c=200
d= 25*25
d= 625
