Question

Tentukan nilai A dan B
a.a:b = 2:3 dan a+b = 150
b.a:b = 3:4 dan a+b =35
c. 25:125 = a:b dan a+b = 6
tolong jawab yang bener,lagi butuh nih. yang cman ngasal terus cman ngincar poin doang nanti dosa lo. mkasih

Answer 1

A. A = 2/5*150 = 2 x 30 = 60 B = 3/5*150 = 3 x 30 = 90 B. A 3/7*35 = 3 x 5 = 15 B 4/7*35 = 4 x 5 = 20 C. 25:125 =1:5 A = 1/6*6 = 1 x 1 = 1 B = 5/6*6 = 5 x 1 = 5

Answer 2

A. a/b = 2/3
   A = 2/2+3 . 150
       = 2/5  .150 = 60
   B = 3/5 . 150 = 90
*bukti : 60 + 90 = 150
b. A = 3/7 . 35 = 15
    B = 4/7 .35 = 20
  
c. A= 25/150 .6 = 1
   B = 125/150 . 6 =  5
