Question

1.)a / 40 = 2 / 16 2.)3 / 9 = b / 15 3.)c / 20 = 5 / 25 4.)18 / d = 57 / 95 5.)2 / 130 = 9 / e HURUF HURUF TERSEBUT UBAHLAH MENJADI SUATU PERBANDINGAN

Answer 1

A:b:c:d;e
5:5:4:30:585

Answer 2

1) a/40 = 2/16
   a=40/16 x 2 = 40/8=5. maka a=5
2) 3/9 = b/15
   b= 15/9 x 3 = 45/9 = 5. maka b=5
3) c/20=5/25
   c=20/25 x 5 = 100/25 = 4. maka, c=4
4)18/d = 57/95
   d=18/57 x 95 = 30. maka, d=30
5)2/130 = 9/e
   e = 9/2 x 130 = 1170/2 = 585. maka, e=585

maka a:b:c:d:e = 5:5:4:30:585
